exim configuration problem

[Hamish Moffatt <hamish@debian.org>]

I'm reconfiguring my local mail setup at home and I've run in to a problem.
I converted one machine from smail to exim, which is working fine (just
a plain smtp/smarthost system). The problem is with its MX receiver,
also running exim.

The target host is known as both hostname.domain1 and hostname.domain2.
The DNS for both domains lists anotherhost.domain2 as the MX.
hostname.domain2 also has an A record, and anotherhost can talk to it fine.
(however, the host is firewalled except to anotherhost.)

However, "exim -bv hamish@hostname.domain1" and the same for domain2
both fail, saying that the lowest MX points to the localhost (which
is correct). In my exim.conf, I have this router:

known_smtp_domains:
  driver = domainlist
  route_list = "hostname.domain1 hostname.domain2"

I thought this would do the trick; I've used something similar for another
domain and it worked. hostname.domain2 has an A record, after all.
What am I doing wrong?


thanks,
Hamish (not an MTA guru!)
