Ok but this couldn't cause that if for example you have 20 messages to be redirected for a transport (by the queue manager) and only 4 transport proccesses, it couldn't cause timeouts because you process 4 by 4? > > > I say because sometime have suffered unknown mail transport errors that >> has fixed increasing for example the number of smtp instances in >> master.cf <http://master.cf/> > > I mean when you do mailq : you view the "unknown mail transport error" error... I enabled debug that day and it was throwing socket errors, but it hadn't arrive to socket limits of the OS or descriptor limit, I remember that -vv was throwing errors about sockets that were closing and re-spawning (because of max_use I assume)... although I don't remember it correctly what I wanted to avoid is just this... I want to say only 4 smtp clientes, 10 amavis transports... and not to be timeouts or errores like I described... > >> > No, your observation is flawed.
