Woa!!
Do you have statistics of access/min for pop3?
No, but I 'greped' 2300 logins/minute peak for a given day for *IMAP*.
Indeed it could be premature since I didn't measure any real bottleneck. Just something that got my attention.

Hello All,
I've been studying dovecot for replacing my company's current system and I got a little worried about an aspect of the dovecot's design. I was surprised that dovecot doesn't use prefork for its mail processes, forking a new processes for each new client connection.
Talking in the #dovecot channel I was gave a scenario of a system supporting ~40k users with 4 servers just fine. I wonder how well dovecot would scale if we increase this number of users by some order of magnitude like, say, 4M users.
Well, we have 8 servers for that amount of users.
It is well known that preforking is a good pratice if you want to achieve a higher performance.
Some say it's premature optimization.
When I was asked about it I readily answered: "of course it does". For my surprise later, i doesn't.
Do you have any plans to support preforking in the near future?
