There is an internal DNS server. I can ping the hostnames of both machines
without any problems and nslookup also resolves correctly.
The error message from the exim log gives a verify failed for SMTP
recipient email@??? the exim box has a user with
email@??? could it be getting confused? The wierd thing is the
Exchange server cannot send to the exim box either.
I am kinda puzzled since DNS seems to work fine.
