I'm using multiple instances of Postfix. One of the IP addresses I just started using is blocked by a major provider. I've gone through all the hoops... It's not on any RBLs, rDNS records match the hostname, etc., but I have no indication that this provider has even received my request about the block let alone plans to remove it.
Meanwhile, I'm using "relayhost = [IP-of-other-Postfix-instance]" to
send mail through an IP address that isn't blocked, which kind of
defeats my purposes for having multiple Postfix instances.
What I want to do is configure an alternate transport for this domain
like...
/etc/postfix-asciiking/main.cf:
transport_maps = hash:/etc/postfix-asciiking/transport
/etc/postfix-asciiking/master.cf:
blocked unix - - n - - smtp
-o relayhost = [IP-of-other-Postfix-instance]
/etc/postfix-asciiking/transport
earthlink.com blocked:
mindspring.com blocked:
When I tried this, I did postmap on the tranport file and postfix reload
for that configuration, but the logs clearly showed the asciiking
Postfix instance attempting to make direct delivery to Earthlink rather
than handing it to the other instance for delivery. I'm trying to follow
"Configuring an Alternate Transport" from p 403 of 'The Book of
Postfix'. Is my transport misconfigured? Is transport_maps the right
main.cf parameter? Something painfully obvious?
Thanks,
Chris Babcock
