I mistakingly entered
virtual_transport = smtp:loadbalancers.example.com:24
^^^^
and got a few messages bounced:
Aug 31 10:12:01 mailgw1 postfix/smtp[32598]: E6A2490076:
to=<m...@example.com>, relay=loadbalancers.example.com[192.168.42.15]:24,
delay=0.03, delays=0.02/0.01/0/0, dsn=5.5.2, status=bounced (host
loadbalancers.example.com[192.168.42.15] refused to talk to me: 502 5.5.2
Unknown command)
I'm a bit surprised that it lead to a 502, instead of a temporary
error. Is there any way to change this to a temporary error and
have it retry at a later point? It would be nice if the mail-serves
can queue the messages when all my lmtp-servers are down...
