Re-read what I said. :) I have 35-40 incoming SMTP sessions at a time for
~16 hours a day. I have my limit set to 100. The tcpserver and
qmail-smtpd processes come and go, except for the one started by
supervise.
Here is my start-up line:
/usr/local/bin/supervise /var/run/qmail-smtpd \
/usr/local/bin/tcpserver -x /etc/tcprules.d/qmail-smtpd.cdb -c100 \
-v -uxxx -gxxx 0 smtp \
/usr/local/bin/rblsmtpd -b -r dul.maps.vix.com \
/usr/local/bin/rblsmtpd -b \
/usr/local/bin/rblsmtpd -b -r dssl.imrss.org sh -c '
/var/qmail/bin/qmail-smtpd
cd /var/qmail/autoturn
exec /usr/local/bin/setlock -nx $TCPREMOTEIP/seriallock \
/usr/local/bin/maildirsmtp $TCPREMOTEIP autoturn-$TCPREMOTEIP- \
$TCPREMOTEIP AutoTURN' 2>&1 | /usr/local/bin/accustamp | \
/usr/local/bin/setuser qmaill /usr/local/bin/cyclog /var/adm/smtpd
This server is THE mailserver for a medium sized ISP. I expect my load to
be different on my machine at home which also runs qmail and different
from your list server.
My home machine rarely has more than 2 tcpserver processes running at once
and even that is rare. The machine just does not get the SMTP traffic.
This server has easily handled ~150,000 messages in a 24 hour period in
addition to several thousand POP3 and IMAP sessions. I expect it to do
better after I get Cyrus out of the picture. :)
