Currently all mail which goes through bastion (for example all
@fedoraproject.org mail) then relays through
mx.util.phx.redhat.com.
So, if we look at our mail route it is:
primary mxes for
fedoraproject.org are:
;; ANSWER SECTION:
IN MX 40
smtp.fedora.redhat.com.
IN MX 10
mx1.fedoraproject.org.
IN MX 20
mx2.fedoraproject.org.
IN MX 30
mx3.fedoraproject.org.
Which are all
redhat.com boxes. So our mail goes from there, to bastion
to expand out the aliases we have (ultimately) then back to
mx.util.phx.redhat.com to be relayed out to the rest of the world.
For various reasons mail bound from bastion to @redhat.com addresses
probably needs to go through
mx.util.phx.redhat.com, however, mail not
bound for @redhat.com shouldn't have to.
I'm proposing using a postfix transport map which explicitly says:
.redhat.com
smtp:mx.util.phx.redhat.com
redhat.com smtp:mx.util.phx.redhat.com
* :
This says:
for mail bound to
redhat.com or
anyhost.redhat.com - relay to
mx.util.phx.redhat.com
for any other email, relay normally (ie: by the destinations normal
paths)
So my question for all you nice people is:
Can anyone see any problem with doing this? I've tested it out on a
different mail server I take care of and it works fine.
