Hello,
Last saturday we migrate our email server from a Sun E250 (with 2 cpu)
to a Sun E450 (with 2 cpu too). In the migration process, we also
changed from qpopper to courier IMAP (migrating from mailbox format to
maildir format in the mailboxes).
The problem we have now is that we have a lot of performance problems
with the new configuration. We have about 4500 email accounts in the
server.
In the more traffic hours, our users have a lot of timeouts messages,
not connecting to the server. They tried, but they can't connect to the
server.
We thought that the problem could be that we have a MAXDAEMON too short
(200) and we have increase it up to 1000 concurrent daemons, but the
problem still appears.
Any idea?
