Postfix handles big concurrent connections very well in SMTP level.
As you know, more than %60-70 of spams are dropped at smtp level via
RBL, rcpt verification and greylisting. so smtpd service performance
is very important.
If there is a way to daemonize qmail smtpd processes or to fix of
this issue, I belive that qmail will be more faster.
Any idea?
Hello Ibrahim,
The load that you observe, where does it come from.. raw processor
chewing or I/O?
Have you seen qmail-smtpd processes consuming huge ammounts of CPU?
Are you using an alternate qmail-queue? Is that alternate qmail-queue
process responsible for eating all your CPU?
Are you sure all the RBLs you're consulting are replying in time?
Mind if i ask how many user accounts and an estimate on the amount of
accepted messages per day?
Regards,
Hugo Monteiro.
