 bitten by rewrite
we rewrite postfix config on startup - because we have an admin UI around some postfix config. In the case of relayhost, we definitely have that in the admin console - you should set it there, and the value will propogate to postfix main.cf (postfix stop; postfix start will also do it).
You can also set the relay host with zmprov command line utility - by setting the zimbraMtaRelayHost attribute on the server objects (or global config). That is what the admin UI does too. This value is read on postfix start and stored into postfix config. |
