mysql:
You aren't using innodb tables. Not Good (tm). You should.
dbmail:
NCHILDREN: You want to raise the NCHILDREN setting. Until my dynamic preforking
patch is applied to CVS, NCHILDREN determines the absolute number of children
forked on startup, and thus, the number of simulaneous connections. Since you're
running webmail only, that means one connection per client, but if you
accomodate clients like mozilla; they use up more than one connection.
MAXCONNECTS: after MAXCONNECTS connections a forked child exits and restarts.
This will help prevent memory leaks get out of hand. There's very little
overhead in having child processes restart more often. 100 is probably a good
enough setting. But then, perhaps all those leaks were flushed out during the
2.0 cycle...

Hi People,
Sorry for all the questions recently, but i am new to DBMail and wan't to make
sure i have it set up perfectly.
I am going to be running with around 11,000 users on a P4 2.8ghz with 1.5gb Ram
(Webmail via IMAP only).
It looks like i am going to be using dbmail-smtp for the moment, but may be
moving to the lmtp in the future.
My main concerns are the way i have my my.cnf and my dbmail.conf file set-up:
MY.CNF:

socket = /var/run/mysql/mysql.sock
