Hello everyone. I want to use postfix as frontend for a amount of non postfix mail server ( old CGP ) with a huge trafic. Right now I'm testing this scheme with two backend servers. Postfix doing all antispam work, greylisting and after verify recipient by verify trasnport (on an already known domain list) send letter to CGP servers. Almost all work as expected. Due huge traf I certainly want use smtp cache with high timeouts. That's ok. But as I see in scache logs (hit ratio), verify transport don't use already established connections pool and makeing it's own. Is there any workaround to make verify use scache?
P.S. I agree, it's not very good way to check exist of recipients, but they changes more often, than domains, so I can't just rsync it from export of CGP conf.
