I managed a 30GB DBMail installation ( mysql storage engine ) for a couple
of years. The performance was stunning compared to our old file-based IMAP
server. Also the hardware was very modest - an Athlon 2000XP with IDE RAID
disks ( cheap bastards wouldn't give me a decent server ).

I can't complain about DBMail in this setup really. You already know that I
recently posted regarding an issue backing up our DBMail database from
MySQL. This is still unresolved. I posted to the MySQL mailing list, and
some people have responded saying they have the same issue. I wonder
whether MySQL is a good choice, especially looking forward ( I'm a
long-time MySQL user, by the way ). They've been bought by Sun ( who aren't
going so well ), and InnoDB have been bought by Oracle ( who aren't
interested in pushing development of a competing product ).

Anyway, there haven't been any noticable slowdowns in the above system as
the database grew. YMMV.

I'm running two locations, one with 60+Gb, the other with 55+Gb. Both
running exceptionally well with over 4000 users each turning over about
30,000 emails / day (That's deleted mails taken from the dbmail-util
purge script, so more than that are actually retained). Most of these
are POP3 users but some heavy IMAP users also.

Josh.
