Some possibly related doc snippets; http://www.postfix.org/transport.5.html ... In the case of SMTP, specify a service on a non-default port as host:service, and disable MX (mail exchanger) DNS lookups with [host] or [host]:port http://www.postfix.org/postconf.5.html#smtp_address_preference ... The setting "smtp_address_preference = ipv6" is unsafe. It can fail to deliver mail when there is an outage that affects IPv6, while the destination is still reachable over IPv4. Sorry for the generic help, but that kind of goes along with the generic problem report. If you need more help, please see http://www.postfix.org/DEBUG_README.html#mail -- Noel Jones
