i ve a mail server to manage with some email accounts but with multiples users (+50) using a common email. it indicates sometimes that it can't connect cause too many connections.
what are the good options to allow a lot of users for a specific account ?
i modifyied these options : auth_worker_max_count = 60 mail_max_userip_connections = 60
is it sufficient ?
Probably not, but it depends on the mail client they are using. Some mail clients chew up 3 or 5 concurrent connections per session. MacOSX Mail.app will consume all the connections while doing global pattern searching (i.e. if you allow 200, it will open up 200 connections at a time before closing them).
If your users use POP3, then the limits have a good chance of working.
If too many concurrent connections becomes a problem, maybe you can use mailbox sharing rather than single account access.
