Hi Jeremy:
Thanks for replying.
We're using spamc in a maildrop filter called for each pop account (via qmailadmin's spam enable setting). User SA prefs are maintained by. MySQL
Good suggestion on the catch-alls - we'll do a scan for accounts with many emails. We do have some with 10 to 15,000 emails. ReiserFS was not an option on RH8.0 unfortunately.
We've got 28,000 emails in the queue - not preprocessed is zero.
- concurrencyincoming = 30
- debugging is turned on for qmail-scan (seems to be the only way to generate a log of all messages processed) but the log is closed and zipped each night.
- smtpd log shows we're using about 15 of the 30 incoming connections.
- softlimit in /var/qmail/supervise/qmail-smtpd/run is 30MB
- vpopmail is configured for MySQL auth with all domains in one table.
- we use mfcheck and the checkuser patch (mysql) to drop questionable connections.
I don't know what you mean by 'conf-split' or big-{ext-}.

are you using spamd and having qmail-scanner call spamc? or is it calling spamassassin. if the latter, change it to spamd/spamc model, much more efficient.

with ext3 you have to be careful about catchall accounts, and accounts that nobody checks that get a lot of email. If there are say, 25000 messages in an account and it gets 100 messages per hour, that will bring your server performance down quite a bit.
of course, using reiserfs on the mail store will fix that problem. I've had over 150k emails in one account with reiserfs, and the system wasn't even being phased as I pumped more mail at it (was load testing for a customer)

what is the approximate queue load, and what is your conf-split value?
do you have big-{ext-,}todo?
