I'm looking to replace our aging Windows email server at work. I'd prefer to use Linux for it's flexibility and no licensing issues, but looking around there's a bewildering number of packages. Does anyone here run a Linux mail server for their business? What packages did you end up with? Thanks David.

basically kolab. Stuart.
Thanks David.

What kind of mail server do you need? Do you need pop or imap? do you need webmail or not? how many users do you have? will you be doing virus-scanning and spam filtering or not? what hardware will you be running this server on? how much mail do you deal with? Sorry to be so useless, but the answers do sort of depend on some of these. Obvious one size fits all answer for me would be Exim+teapop or dovecot +clamav and spamassassin (although, spamassassin seams to have run out of steam for me, anyone got any good anti-spam software suggestions?)

OK sorry to be so loose in the spec. Basically looking at around 150 people who need POP3 access, no webmail needed and some external users could look at using IMAP+SSL. * Virus Scanning is a necessity as are mailing lists * spam-filtering would be good (although we already have Brightmail filtering at the ISP-level). * The hardware is yet to be decided, but something quick ;-) * Haven't established exact mail counts, but possibly around 1000-2000 a day (mostly internal)
(although, spamassassin seams to have run out of steam for me, anyone got any good anti-spam software suggestions?)
I'd be interested in suggestions too, I understand that bayesian-filtering doesn't scale well in corporates? Cheers David.

No problem with any of that. Postfix, Courier, Amavisd, Spamassassin, ClamAV, Squirrelmail (if you need external web-based access, requires IMAP). Would recommend you use IMAP as then incoming and outgoing email can be backed-up and shared if required.

Works for us. We use Rules-du-jour, updated regularly, to keep the extra rules up-to-date. Gentoo (our preferred platform, has an ebuild for that.

There are ways of doing it, but it requires user input/effort, which is often lacking. The downloaded rules are pretty good, IMO. Frankly, using the RBLs is the best way, but it can be a bit blunt. wanadoo, for instance seem to be relisted with boring regularity, and a lot of UK people use them.

I've had dspam recommended to me, but not actually had a look at it yet. Exim+dovecot+clamav are all good IMO. Though I've found Courier a reasonable IMAP/POP3 server too.

Having tried qmail and battled with sendmail I finally ended up with postfix which, for a small SoHo network I found the easiest to configure. -- Chris Green (chris@areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

I use postfix+courier+amavis+clamav+spamassassin+mysql+squirrel Using mysql mean you have virtual users and not those pesky real unix accounts. It also depends on what hardware you have, spam and av scanning can be expensive. I mostly followed this howto http://genco.gen.tc/postfix_virtual.php but alter it for your own needs Cheers Stuart -- The problem with the world is stupidity. Not saying there should be a capital punishment for stupidity, but why don't we just take the safety labels off of everything and let the problem solve itself?

Yeah, I forgot to mention that. We use virtual accounts in mysql as well, and it works really well, making management a doddle.

Yes, true. We've found that using a virtual disk helps a huge amount with scanning for spam and viruses. Memory is relatively cheap these days, and considerably faster than a physical disk.

If you want to do it yourself there's a cracker on the Gentoo web site: http://www.gentoo.org/doc/en/virt-mail-howto.xml http://www.gentoo.org/doc/en/mailfilter-guide.xml We've adapted that a fair bit but essentially that's what we do.

Almost always exim (but there are some sendmail and postfix here) and quite often solid-pop3d (because of APOP and PAM) but I will try dovecot and some others Real Soon Now because solid strains with mailboxes bigger than 40Mb (yes, bloatware attachments, I know, but on internal network mailservers that's not too unusual).
