Gentoo Mailserver

-leliel- · Posted: Tue May 13, 2003 3:52 pm Post subject: Gentoo Mailserver

Hi,

I want to build a Postfix + Ldap + Courier IMAP + Anti Spam Mailserver on Gentoo. Is anybody experienced in this?

If all works fine, I'll try to write a howto for the tips and tricks section, too.

My mail server is Postfix + Courier-IMAP + Procmail + SpamAssassin + Squirrelmail. I'd wanted to use LDAP for virtual mail (or MySQL for the same), but never did get it working.

There's a How-To for virtual mail that can easily be modified for single-host mail, in the Docs section on the main Web site.

Thanks for the hint. I also found a howto for postfix + lpap, but maybe this could be made easier with some use flags etc.

Could you shortly explain what virtual mails are and what problems you had with ldap?

thanks

virtual domains and virtual mail serving is where you host more than one domain from the same box using the same server. For example, if I was a web-hosting company, I might have one computer handling all the email for companya.com, non_profitb.org, and hobby_siteC.net on the same computer using the same server. That's pretty much all there is to it.

I've got 2 production gentoo anti-spam mailservers running currently.

I'm using the following packages to accomplish it:

Fetchmail
Courier-Imapd (And pop3d)
Maildrop
Mail-SpamAssassin
Squirrelmail (and apache of course)

I haven't messed with LDAP yet... and I'm not even sure where to start on that... but I can help with any of the above packages as far as my config goes.

I've also got a set of bash scripts I wrote that provide stats on the spamfilter, and generate hourly updates to a stats file on my webroot. I'd be happy to share the sources from that with you as well.

so, I'm workin' on an LDAP at the moment ... I found a HowTo named 'LDAP for Postfix with Courier IMAP' with useful information about ldap and ldap directories. As soon as I got the ldap running I'll begin to write the HowTo and set up postfix a.s.o..

I'm just using postfix at the moment:

main.cf:
http://www.dmatech.org:8000/~dma/pf/config.txt

access:
http://www.dmatech.org:8000/~dma/pf/access.txt
(I removed a few entries).

It seems to kill spam quite nicely without spamassassin.

Hi,

thanks for the info ...

my only problem at the moment is as follows:

there's a mailserver at my isp. this mailserver collects all mail from different domains and I could recieve it.

Now, I want to install my own mailserver, get all this mails from the remote mailserver and process them to the local users (accessible via imap). What do I need for this configuration? virtual boxes?

I have an essentially similar configuration and use the following set-up:

fetchmail runs from a crontab entry as a non-privileged user to retrieve e-mail messages for all users from pop and imap servers
procmail is invoked by fetchmail as the local mail delivery agent (mda)
procmail filters stuff through spamassassin first and then forwards email messages to local users through postfix' local delivery agent
courier-pop3d is set up to be the pop-server for local users

A few config files to fiddle with, but not very hard overall.

Well, i know i might be a lil late on this but a very close config. to what you want to achieve is posted on the main doc page at postfix.org. Lemme fetch the link:

Postfix+MySQL+Courier-IMAP+Maildrop+SpamAssassin howto by Serge Stepanov: http://www.gfxcafe.com/Mail%20Howto.htm

A very good place to start with nice and well written howtos is the doc/howto page from postfix.org (look under the POP/IMAP section, the link above is from there):
http://www.postfix.org/docs.html

Cheers, i hope this helped a bit,
