To be honest, I don't see what exactly has changed here. Manual pages from a stock Postfix 2.6.5: ,----[ man 5 access ] | FILTER transport:destination | After the message is queued, send the entire message through the | specified external content filter. The transport:destination | syntax is described in the transport(5) manual page. `---- ,----[ man 5 transport ] | A non-null transport field with a null nexthop field resets the nexthop | information to the recipient domain. `---- If my question is answered in other parts of the documentation, I apologize in advance.
