We recently upgraded from exim3.36 to 4.24,
We used the scripts that come with Exim to
rewrite our old exim configure file for the most part
and they seemed to work fine. Our server reads from
a domain file and an aliases file (both .cdb's)
and then forwards mail based on what is in the
aliases file. Since the upgrade, A very high percentage
of deliveries are displaying this :
lowest numbered MX record points to local host: domain.com (while verifying
<wqew@???> from host (uuuu.net) [193.79.xxx.xxx])
now domain.com is in our virtuals file, and we want to
accept mail for it and forward messages to domain2.com
in this case. I just don't really understand what took
place during the upgrade that would cause this.
Any suggestions? I will include our 4.24 configure file
below. As well as our exim 3.36 configure file.
Thanks in advance
Nick
