Not relevant, but the above line isn't needed (since Postfix 2.11).
I commented this out.
mydestination = $myhostname, ca2ceus.wtfayla.net, localhost
Does the value of $myhostname refer to the primary MX host by any chance?
If so, the above line would cause the secondary MX host to deliver locally.
But that's probably not it (if all occurrences of <hostname> refer to the
same hostname). The certificate there is for the host name
ca2ceus.wtfayla.net (presumably, the secondary MX's public hostname).
Just looks like I forgot to s/ca2ceus.wtfayla.net/<secondary hostname>/g
for one instant. Now that the cat is out of the bag, caduceus.wtfayla.net
is $myhostname, and ca2ceus.wtfayla.net is just a CNAME to the former.
relayhost = #mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
The line above looks wrong. Comments only start at the
start of a line (after spaces/tabs is ok). If this is
the cause of the problem (i.e., postfix trying to relay
to an incorrect hostname), there would probably be log
messages to indicate that. But that's probably not it
either. Postfix wouldn't deliver locally if it thought
it was supposed to relay but failed.
Turns out it's just a case of carriage returns somehow getting lost when
pasting into the email. It really looks like this:
relayhost =
#mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
#mynetworks = 127.0.0.0/8, 174.138.48.1/20
But that means that relayhost is empty. Should it be set to $mynetworks?
transport_maps = # hash:/etc/postfix/transport_maps,
mysql:/etc/postfix/mysql_relay_transports.cf
The apparent comment above is also wrong. Move it to a line
of its own. Perhaps that's relevant if transports are used
to relay to the primary MX host.
Same deal with the email formatting. It really looks like this:
transport_maps =
# hash:/etc/postfix/transport_maps,
mysql:/etc/postfix/mysql_relay_transports.cf
I hope that helps a bit. But it might not be enough to
solve the problem.
cheers,
