Howto: set up a mail server in Ubuntu

[flurdy]

The how to set up a mail server on a GNU / Linux system guide has been upgraded to breezy from hoary.

It is a complete step by step guide to install, configure and run these packages:
Ubuntu + Postfix + Courier IMAP + MySQL + Amavisd-new + SpamAssassin + ClamAV + SASL + TLS + SquirrelMail+Postgrey

Please discuss in this thread any issues or comments regarding this, the 4th edition.

Specifically the SASL section might need testing, as some of the packages has changed since hoary.

Edition 3, the hoary version, is discussed in this thread . Some issues might have already been discussed in that thread.

Thanks I have my mail server running with breezy.

php4-pear
php4-cli

Missing from document as required installs. I did go back to 3rd addition to locate them.

Thanks

Updated the SASL packages so it works perfectly in breezy

Great - as I am about to set up exactly this thing, I guess, it will save many hours of doc-reading and google.
Thanx.

flurdy, this all seems pretty cool and all, but I can't set up the shorewall, there's only a shorewall.conf inside the directory, I dunno if I missed something (can't start up the firewall because it says no zones are defined)

see the os section of the configure bit

Great Howto!!!

I have set this up on my server, however I had hit a small snag. Postfix as of 2.2 I believe, has TLS support built in. However according to Postfix's website, it is turned off by default. Therefore there is no Postfix-tls package in any of the breezy badger repositories. (This sent me for a loop untill I found out it's built in now)

Flurdy, thanks for the great HOWTO.

I started with a fresh Ubuntu install and worked my way through your setup from top to bottom but I've run into a small snag. While testing in a telnet session I get an access denied error in mysql.info immediately after closing the data field of the email. Postfix@localhost.localdomain is trying to connect instead of the mail user I setup in sql and in all of the postfix_*.conf files. This test is with all content filtering turned off. If I turn the filtering on, I get a different error (Can't connect to 127.0.0.1 port 10025, Connection refused at /usr/sbin/amavisd-new line 2912, <GEN9> line 34.) but in exactly the same spot.

What have I buggered up?

by postfix_*.conf i presume you are using a different naming convention than from the howto. are there other lines in your set up that could be using mysql?

could you post the relevant lines in main.conf and the mysql cf files (without the pw offcourse)?

as for the amavis errors, have you specified it correctly in the master.cf?

[rabid]

My bad...had postfix on the brain. postfix_*.conf = mysql_*.cf. I did however get the original problem worked out. I had a spelling error in mysql_mailbox.cf. userr=mail. I'm gussing this caused it to default to postfix@localhost for a user. Still getting the Amavis error, but I'll keep troubleshooting that and post again if I can't get anywhere.

Thanks for making me look at my .cf files one last time. I didn't notice the error until I was pasting it into this message.
