Hello, I might have a problem with the smtp_connection cache. Regarding documentation, the cache is enabled on demand by default.
I found a peer site, which is also driven by postfix, with uses greylisting. I have some 3000 mails to send to this particular server, which starts the session by greylisting my server. Since postfix uses the smtp_connection_cache by default, it reuses the connection which receives one greylisting temp fail after the other. This seems to triggers the $smtpd_hard_error_limit on the other site. My server continues to use now dead connection until the cache limits take effect. I tend to assume, that this is a bug and maybe a configurable amount of errors should trigger the sending postfix to abandon a connection. Did i miss any configuration options here or do you agree?
