 Posted: Sat May 06, 2006 9:25 pm Post subject: Exim - Random host lookup? |
 |
|
Peppered thoughout my log is the entry: no IP address found for host mattpc
Now mattpc is a machine on my local network (different subnet). I've setup exim to allow this host:
exim.conf:
| Code: | | accept hosts = paradox : mattpc : mattlaptop |
mattpc and mattlaptop are on a different subnet, paradox is on the same subnet as the mail server.
The two things that bother me is a) this only happens for the host 'mattpc' (not paradox or mattlaptop) and b) the error is generated buy a connection for an external host? I assume exim is trying to resolve mattpc, but why for only certain connections, and why so randomly?
(email addresses have been obfuscated with X.tld)
Here's part of the log:

1) Any ideas WHY this is happening?
2) How do I fix it?
Thanks,
