Linux off-line mailing method (offline mailaddr with 1account) Gunther Voet, - Belgium (CompuMed/TuCSRV) v1.3.1, Mon 15 sept 1997 (CET) Use your linux mailing system offline, receive mail for multiple users with only one email address, and without being 24-24 online on the net. If you are unable to pay a direct line to stay online for 24-24 and still want your users to receive mail on your linux box; as well not pay for a multi-drop box at your isp, you can use this system using only one email address to divide to your users email addresses. It is as well 24-24 reachable since the server where your account resists will receive the mail. Notes by the author (preface).

In this chapter i'm just going to put myself safe for any damages and flames - since even *I* could be wrong ... If you got any questions or suggestions to add to this faq, even if you find any faults - there is a feedback section in it ...

Some "need to know" point is, all filenames & files/types are indicated with the line:

`(*** < file > *** text ***) .procmailrc`

This means, this is a file, called ".procmailrc" containing text. The text variable can also be code. It shows you what name of file to use. Without a path means it can be variable/choosen by you (in the most cases this files resists in the homedirectory of the mail"user" like /home/mailer). Legal stuff

The latest revision of this document can been get from: -and- -and- (when the server gets back) (also checkout ) Changes

v1.0.0 - Preliminary release, internal testing, we tried it before we gave it out to you :) .. since - it GOT to be usefull and needs to work? rite ? :) v1.1.0 - Fixed a lot of errors in the texts, put chapters in it, - fixed some small errors and typo's ... v1.2.0 - fixed grammatical errors. - added a "what-are-we-using" chapter. - added Sunsite address. v1.3.0 - Added "virtual mail support" for admins - New site and email addresses - Thanks go to ... v1.3.1 - Converted to SGML and fixed some minor details. What am i using ?

I'm using Linux 2.0.30, Pentium-166, ATI pci-mach64 card, Accelerated-X (Metro) and a connection to my isp (currently ibmnet) via ppp using a ZyXEL 28k8 modem, and occasionally a Bausch 28k8. Thanks go out to ...

Fred, durban.hebel.net (for allowing the pages & bot) Lifesaver, parkside.net (for allowing the new pages, helping with this faq for mailing, since, it is all working overthere and here ... make some visit to his cyber-cafe ... heard they got great coffee :)) Preliminaries

Well, how does this system works ? what can you do with it ? what is it anyway ? and ... am i used to read it ? ... to all those questions - there is an answer ... Preface & Description

This HOWTO is dedicated to all the off-line linux users/servers ... You got a group, or organization, and you want all your members to have a contact (email) address, without paying for the 24/24 direct line or for the email accounts ... Or you got a internal network - with a masq'd server and you want to give all the users using it a email address, you could use this way to do it. I personally am using it to give my users & members of a demogroup all a e-mail account without being 24/24 online; since it is a non-commercial demogroup - and we don't got THAT much money to pay a direct line with instant email access - and different ip's. Everybody got a email address, even when they don't got internet access. The ones with internet access can receive their mail on their personal email address - viavia the system described below. Your users can still send mail as they used to do, since - your system will hold the mail queue from the users. The only thing what should be changed for the users - is that they add their "email address" wether (described below) it is the method with the subject line, or with the header "to" ... Points of interest ...

A organization with members, for all a email address, so they can be contacted when neccesary. A anonymous mailservice - they can't read your "mail setup file" - so they don't know where the mail is forwarded/rerouted to. A group who doesn't got enuf money (don't laugh), or is free, and don't WANT to spend money for it (eheh) - and still wants to provide the members a email address. A masq'd network - with a server connected to the internet, where the users using the masq'd network need to have a email account You want to put some documents "autoreplied" - like i do with my HOWTO, statistics, or documents ... like "info@yourmail.dom" or "document1@yourmail.dom". You only need one account at the "main" server to fetch from, for the +200 email accounts you can create at your server ... I used the "B" method with +- 300 email accounts - with a public server; 80486DX4-100 - and was processed in 1 minute. Things you should know

Not every (free) mailservice is happy when you are going to distribute mail to other users, or putting up an anonymous mail server, so, please try to contact your mailserver administrator before "just doing it". It is slower than a direct 24/24 connection, since your server will need to get online before it will process the mail. It needs a administrative force to administrate the "mailrouting" and to add the user ... you will need work with it ! - it is not that automatic. (well - i made it "semi-automatic" with my server :) you could try it as well). Bandwidth and space is needed when you got many users - on the mailserver you are working on ... and sure - when they send files - you need to have enough space on it !. All mail will be transferred into "one step" - so - the last mail received on your server will be last sent to the recipient. "first in - first out". In the first method (to:) there is no prob with the usernames - but in the second "cheaper" method - users can't put in a subject line, since that one will be used to send the mail to the recipient. Many users forget to use the "subject" ... - or they will need to know it clearly. If you poll enough for your mail, (for example 4 times a day) - the mail will be sure be delivered to as from a recipient the least every 6hrs. So the processing will go a little smoother. you CAN use it as a "online" mail server as well :) since it will poll for it's mail for every XX minutes. but - when you are online - why using another server ? and not asking your own domain for your own server ? (dough). there are 2 different ways ...

method 'A' - now called "(m(A))". The "mailsystem" will look to the header, and will see to the "to:" line. This is the best way, since it are "real email addresses". You will need another account on some server *AND* you need a DNS (MX) entry (your own domain for instance). If the system administrator wants to help you with that, then there will be no problem !. The system administrator will need to reroute ALL mail sent to your (MX) maildomain -> to your account !. This will take some time for him to do it :) so be really nice to him :)) Thanks to my system administrator (Fred) i got my maildomain and the user- services of my "free" demogroup. It can be a DNS entry costs something, what you will need to consider to take it or not. method 'B' - now called "(m(B))". The "mailsystem" looks to the subject line, and will forward to the user indicated into the subject line. If the user is not found, it will bounce a mail back. This will need a pop server with only one useraccount, and don't need your own DNS or you don't need to be nice to your system- administrator who arranges you the mail address :). You can use a public mailserver, as well your own mailserver or a private one. You can even sacrifice your own email address for it :). I used this approach as first what worked for me for over a year now ... I know this is sloppy, but, i ain't telling you need to use this way, so don't shoot ME - since i'm only offering you some solutions to your mail problems :) - you could use method A what isn't that sloppy ! Requirements

Well, you need (of'course) a Linux machine, what can be connected to the internet - So! (i am smart - i am smart :)) - you probably got a modem, right? a phoneline - or any way to connect yourself with the server you are running. You will also need some software like Fetchmail, Procmail, an extra account, and your email account or DNS with email account. A linux machine

This can be ANYthing ... even a 8086 ... - but preferable - since there will be some load on it - minimally a 80386 :). as faster the machine - as faster the software will run (rite eh)? :). A extra account at your linux machine

You need to create a extra account on your Linux machine. I am using as example (in this HOWTO) "mailservice". This can be as well "mailserver" or "mailtousers" - as long it is some name what can be recognized by you!. ! It doesn't need to have ANY root privileges ! This mailaccount will forward all mail to the users on your system, or to external users (not on your system :)). Just create it as an ordinary user. You will need to test things under this account, and, the mail "administrator" can use this account to administrate the mail account without being root even .. so - pretty safe !. Fetchmail

I am using v1.9 patch level 9 ... i found it at sunsite.unc.edu, and, i am using only this mail-fetcher in my example - if you want to use another one, you are on your own ! since i am happy with it :). For extended features you should read the man of Fetchmail :). This can be installed as root - as well for the user itself ... - best is to install it as root :) since i know it will work for sure then :))) Procmail

I am using v3.10 - found it again at sunsite.unc.edu, and - i like this as the best mda (mail delivery agent) around ... It delivers nicely - and it is better than using it by the "original" system mda - since it will deliver user-per-user ! ... The same as above - it can be installed as root, or as user - and :) best is to install it as root - since i know it will work for sure then (again!) :)... how repetetive ... A mail account

You always need to have a mail account - where you can "poll" your mail from. The server needs to be a POP server - where you can poll from when you want, and where users can send their mail 24/24 to. It can be a free-mail service, as well commercial - even your mailaccount is sufficient enough. In the "subject" method (m(B)) - you don't need something more - in method A - with the "to" fields - you NEED more - as written below ! A DNS record (MX)

Needed to run your own "domain" - email domain ... it is needed since the administrator of the server can't use it's own domain for your users - since there are users who need to be contacted on his server as well - what could interfere with your users. And your mailheader must be filtered on that domain. So - an apart domain - pointing to HIS server. This can be an additional cost - or you can ask your system administrator to add a "non- authorative address" - pointing to his server ... - however - it needs to be another domain than he is using ! A "forward" to your account-account :)

Well, the system administrator needs to forward *ALL* mail to your domain to YOUR account ... - it is easy for him when he knows how to do it :) .. else he will need to read the sendmail manual :)) (or qmail - whatever). You will poll for your mail at your account and voila ! filtering on YOUR own email domain. I got it all, what now ?

Now you created the extra account, you got the mail address - and/or the DNS entry & forwarding to your account ... As well installed Procmail & Fetchmail, we can rock the place ! :) .. here we go ! You need to create a .fetchmailrc file, what will contain the "delivery" info to your users. You need to create a "nosuchuserfile" - so the writer knows his mail isn't delivered well. For best work :) you could use crontab to check for mail. This is a easy way to check your mail every XX minutes when on the internet. Creating a .fetchmailrc file

You will need to create a .fetchmailrc file, what will contain the information (username & password, as well the Mail Delivery Agent (mda) to proces the mail to). Here is some example file ...

`(*** < file > *** text ***) .fetchmailrc` `server my.mail.server.com proto pop3 user myaccountthere pass deepestsecrets flush mda /usr/bin/procmail`

This file will be used to fetch your mail. Please test it by using the fetchmail program "fetchmail -vv" - and see your mail is being transferred right ... There will be some errors - since the procmail control file hasn't been created yet. You can wait by testing AFTER making the procmailrc file, but - i'll warn ya - IF there is something fault :) it CAN be this file :) It needs to be owned by the user account itself - in my case "mailservice" and needs to be "user readable" but NOT group/world readable - since it contains the "main password" :)). (chmod 600 .fetchmailrc will do). Creating a .procmailrc file

This control file will forward all mail to the users in it. There are 2 ways as described before - the "to:" (header) way - and the "subject" (sloppy) way. The file will contain the usernames to transport to. All the "#" are comments and are absolutely not needed when not wanted - it's only so you know what i am doing ... - you can as well best chmod it 600 - so the rest of the world or group doesn't need those private addresses eh :) ... It needs also to be owned by the user (like "mailservice") :)). The "nosuchuserfile" is a "bounce" to the writer - if the user isn't found (so mail not delivered) in the procmailrc file ... - so the writer knows the mail isn't delivered well. For "header (to:)" transportation

`(*** < file > *** text ***) .procmailrc` `# this line is for debugging purposes only ! it should be removed for # ethical purposes - since you can read all mail passed trough your mail- # server ... - all mail will be copied to the file "passtrough" before # going to the users ... herein you can look what went wrong ... :0 c passtrough # the mail with header "to: freaker@mydom.com" will be forwarded directly # to me, the other mail will pass this option ... :0 * ^To:.*freaker@mydom.com ! freaker # the mail to root@mydom.com will be forwarded to root ... as well postmaster! :0 * ^To:.*root@mydom.com ! root :0 * ^To:.*postmaster@mydom.com ! postmaster # the mail to barbara@mydom.com will be forwarded to barbara AND will be # forwarded to her private email address ! :0 c * ^To:.*barbara@mydom.com ! barbara@her.private.one :0 * ^To:.*barbara@mydom.com ! barbara # this lines will BOUNCE the mail to the sender - when it is not delivered to # one of above users ... it will send the file "nosuchuser" into the mail # body as reply ... be aware ! you need to make such file ! - mine contains # "well, the user you wanted to reach does not exist on this server, please # try again, it could be the user is not present anymore". # :0 |(/usr/bin/formail -r -k \ -A"X-loop: mailservice@mydomain.dom "| \ /usr/bin/gawk '{print }\ /^/ && !HEADER \ { system("/bin/cat nosuchuser"); \ print"--" ;\ HEADER=1 }' ) |\ /usr/bin/sendmail -t exit`

For "subject: touser" transportation

`(*** < file > *** text ***) .procmailrc` `# this line is for debugging purposes only ! it should be removed for # ethical purposes - since you can read all mail passed trough your mail- # server ... - all mail will be copied to the file "passtrough" before # going to the users ... herein you can look what went wrong ... :0 c passtrough # the mail with header "to: freaker@ibm.net" will be forwarded directly # to me, the other mail will pass this option ...

"nosuchuserfile"

`(*** < file > *** text ***) nosuchuser` `The user you wanted to contact is not present at this system. Please use the subject line as recipient - example "subject: freaker" would send mail to freaker on this system.`

"crontab files".

If you don't know how crontab works :) better read the manual :) ... You need to create a "checkmail" file - what will see if the link is up, as well the cronfile itself ... - i am using a ppp link :) so - this is an example how to look when the ppp link is up - and to poll every 10 minutes using cron. Looks sloppy - but isn't !. checkformail

the .checkformail file will be called (needs to be executable as well) - and will look if the ppp link is up. If it is up - then it will fetch for mail. Crontab will use this file when you are using the below cronentry ...

`(*** < file > *** code ***) .checkformail` `#!/bin/sh # cd /home/mailservice if [ -f /var/run/ppp0.pid ]; then /usr/local/bin/fetchmail -s > /dev/null 2>&1 fi`

crontab

This cronentry file needs to been loaded into crontab, and will call the .checkformail - every 10 minutes. It won't write any mail or give any info to the console - since i'm redirecting everything to null.

`(*** < file > *** text ***) cronentry` `0,10,20,30,40,50 * * * * /home/mailservice/.checkformail 1> /dev/null 2> /dev/null`

"At the admins site".

Well, this should be done when using the "A method" ... at the admin's site, so the email goes all from a complete domain, to one username. It is pretty simple, and once you've done it - it works like hell. this is NOT neccesary if your system administrator (the uplink) got another method, and is NOT neccesary at YOUR side !!!! add some lines to sendmail.cf

add the following lines to your /etc/sendmail.cf file, so the domains file will be read. please be noted that the "ruleset 98" is added as underhere, since - once you got errors :) it's a hell to find 'm out ! (and i can know it :) DuH).

`(*** < file > *** add ***) /etc/sendmail.cf` `# Database of handled domains Kmaildomains btree /etc/maildomains.db # Add these lines *IN* Ruleset 98 ! (under Ruleset 98). R$+ < @ $+ . > $: $1 < @ $2 > . R$+ < @ $+ > $* $: $(maildomains $1@$2 $: $1 < @ $2 > $3 $) R$+ < @ $+ > $* $: $(maildomains $2 $: $1 < # $2 > $3 $) R$+ < @ $* > . $: $1 < @ $2 . >`

creating a /etc/maildomains file ...

First create a /etc/maildomains file, what will be used to "send" a domain to a specific user ... here is an example ... (as you already knew, the name "mailservice" can be anything you want - it can even be your loginname (like mine is freaker).

`(*** < file > *** text ***) /etc/maildomains` `mydomain.dom mailservice`

let it work !

now you'll need to generate the btree (database) files. do the following:

cd /etc makemap btree maildomains < maildomains

after that, kill the sendmail daemon, and restart it. it should now WORK! good luck :) Automation

Well, now, everything above works ... (if it doesn't work - don't even think about automation before it WILL work ... - now - we need some script so it isn't a pain in the ass for the "mailadministrator" or the root user to add users to the procmailrc file ... The below example will be for "more experienced users" - since some things NEED to be changed as well ... - it is an example with the "B method - Subject lines". It can be easily adapted to the "A method". Since the "B method" will be more used (cheaper) than the "A" method - i decided to use the "B method" ... Am i sounding repetitive or not ? .. well - i meant to write it in this way :)) to bug you :))).. The "skeletion".

Since the footer needs to be as footer (everything below won't be processed since we are bouncing there); there needs to be a header and a footer file. the ".procmailrc-header" file

This file will now be the "header & user" file .. since here will users been added and removed - it will be a important file ... - best take a backup from it each time you add a user ... - there COULD be something wrong sometime .. A system can fail ...

`(*** < file > *** text ***) .fetchmailrc-header` `:0 c passtrough :0 * ^To:.*freaker@ibm.net ! freaker :0 * ^Subject:.root ! root :0 * ^Subject:.barbara ! barbara :0 * ^Subject:.paul ! paul@his.personal.emailaddress :0 c * ^Subject:.john ! john@his.personal.emailaddress :0 * ^Subject:.john ! john :0 * ^From:.*newsletter@ibm.net ! freaker :0 * ^FROM_DAEMON throwaway`

the .procmailrc-footer file ..

As mentioned above, this file needs to be as footer - since all data BELOW it won't be used to deliver - this footer contains the "bounce" code to bounce the users not found *ABOVE* the footer !. it is the ABSOLUTE end of the file !

`(*** < file > *** text ***) .fetchmailrc-footer` `:0 |(/usr/bin/formail -r -k \ -A"X-loop: mailservice@mydomain.dom "| \ /usr/bin/gawk '{print }\ /^/ && !HEADER \ { system("/bin/cat nosuchuser"); \ print"--" ;\ HEADER=1 }' ) |\ /usr/bin/sendmail -t exit`

addmail script

This script will add a user to the header file, attach the header & footer to eachother - so it will be a complete .procmailrc file. the "#" (comments) are not really needed - and are for your info :).

`(*** < file > *** code ***) addmail (* chmod 500 *)` `#/bin/sh # # Copyright (c)1997 by Gunther Voet. rev 1.0 # please leave the Copyright in it when it is distributed with any # system using this thingy ... echo "" echo "Addmail v1.0 by Gunther Voet, Freaker / TuC'97 (21/04/97)" echo "" if [ $1 ]; then if [ $2 ]; then # make a backup file ! cp /home/mailserv/.procmailrc-header /home/mailserv/.procmailrc-backup # APPEND (>>) the information to the header file ... echo ":0" >> /home/mailserv/.procmailrc-header echo "* ^Subject:.$1" >> /home/mailserv/.procmailrc-header echo "! $2" >> /home/mailserv/.procmailrc-header echo "" >> /home/mailserv/.procmailrc-header # copy the header file to .procmailrc - and append the footer file to it ! cat /home/mailserv/.procmailrc-header > /home/mailserv/.procmailrc cat /home/mailserv/.procmailrc-footer >> /home/mailserv/.procmailrc # make sure it is owned by "mailserv" and the read/write priveleges are ONLY # for the user "mailserv" itself ... chown mailserv /home/mailserv/.procmailrc chgrp users /home/mailserv/.procmailrc chmod 600 /home/mailserv/.procmailrc else echo "No DESTINATION mail address has been given ..." fi else echo "usage:" echo "" echo "syntax: addmail from_user to_user(domain)" echo "" echo "example: addmail freaker freaker@myemail.dom" echo "" fi`

Now, this script will append the information of the user, as well the email address to the header file, it will copy it to the .procmailrc file, and will add the footer to it, so you got a complete .procmailrc to process the mail. If you want to delete a user- just edit the .procmailrc-header file, and at the next user added it will be deleted at the .procmailrc. To do a instant delete, just delete the user from both the files .procmailrc & .procmailrc- header. Help! (sigh)

Well, you need help - isn't :) ... hmm .. i could be sarcastic and just say "you could better do it again, 'coz it looks a messy enuf" - or .. i could help ... - I wrote down some common problems - IF you got any problem NOT listed in this HOWTO (section) - then mail me - and i'll put it in this howto even with your name/email addr in it :). **BEFORE** mailing to me - please look if you didn't forgot anything - and IF you want some help from me - send me the MOST DETAILED information - included the scripts & things you needed. i DON'T need any binaries - since i won't run them.

The automation script just doesn't work:

is it executable ? is your (default shell) located at /bin/sh ? What do you mean by "anonymous mailserver"?

Well, you could make accounts like "anon0001@yourdom.dom" - and forward it to another email address ... nobody needs to read the .procmailrc file, so YOU ONLY know the address !. My cat died

Well, next time don't print this HOWTO out on 200 gram papers, since it are 10 pages it would be 2KG for the cat - it is JUST TOO HEAVY ! My dog died

hmm - can't do anything about that one - why askin' me ? ... Just bury it .... Linux?

A free-unix - posix compatible - made by Linus Torvalds ... Why are you reading this if you even don't know what Linux is ? Can you help me with finding a mail account?

No! - this is a howto for YOUR side, i don't care about the side of your isp, nor how to get your email address. Why is the "maybe later i'll make some addition ..." removed ?

Read point 5.5 very carefully :) and you'll see why .. it's 'coz i needed to add it on general request :) How do i get a "domain" ?

Ask your local ISP/provider - he will help you with it. It could take days/ even weeks when asking to the Internic - your provider can help. Why are you so f*cking lame using this?

`coz i don't want to spend money - and - 'coz i feel like being f*cking lame USING it - i *AM* using it - so why bother? Nosuchuserfile?

You can put in it what you want - as long you put some "needed" info so the original writer knows what happened with his "never delivered" mail. Can my users write/send mail too?

This has nothing to do with the system i explained to you, read the sendmail manual ... - this is to RECEIVE mail - to be "always available at an email address". Does every user need a shell account at my server?

Nope .. - but - it will be really hard for users not having internet access :) ... You could have a masq'd network - and use a computer connected to it - so the users can get their mail that way, or you can generate a link between a bulletin board and his mail, you could even forward it to a fidonet gate :) ... reasons enough not to give a shell!. skeletion?

i know it is a typo - but - i like this word better. Addmail?
