I have been talking about smtp client threads of postfix... but imagine now (for understanding better...) amavis for example... you launch two amavis processes as you specified in amavisd.conf. So if you set the proccess_limit for amavis to 2 in master.cf <http://master.cf> you shouldn't never have a transport timeout or any kind of error for waiting messages in active queue till amavis has a free proccess for accepting the message? the only thing could happen is that the active queue reaches the limit of messages in this queue and later are deferred instead of going to active from incoming?
See the README.postfix included with amavisd-new for details on setting up amavisd-new with postfix.
- The number of postfix smtp processes feeding amavisd-new must be less than or equal to the number of amavisd-new processes running. - The number of postfix smtpd processes receiving mail from amavisd-new must be equal to or greater than the number of amavisd-new processes. - Amavisd-new must be able to process messages in less than postfix $smtp_data_done_timeout seconds, usually set in master.cf for the smtp feeding amavisd-new.
If the above conditions are met, there should be no timeout errors regardless of the amount of mail queued, up to the limits of the machine. All mail will stay in the active queue, up to $qmgr_message_active_limit.
