Hi,

I'm struggling with new SMTP server and I noticed that sometimes it just
hangs because of:

Jul 2 14:14:21 smtp postfix/master[17716]: warning: service "smtp" (25)
has reached its process limit "50": new clients may experience
noticeable delays
Jul 2 14:15:06 smtp postfix/master[17716]: warning: to avoid this
condition, increase the process count in master.cf or reduce the service
time per client

The problem is when it happens I can't do nothing just reload postfix.
Is there any way to sort it out ? I increased that value now, but for me
it's not solving my problem because instead of increasing that I would
rather like to postfix struggles with with on its own somehow by reload
configuration or ... I don't know.
Maybe is there any timeout to setup, because after that when I took a
look at netstat it showed me a lot of connections from 127.0.0.1
(greylisting daemon).

Thank you for any help in advance.

Regards,
Jarek
