No HOSTS file is present.

Using UU.Net's DNS servers for the IMAIL server changed to local, no
difference.

Maybe you are mis-undertanding, many times the www server has an smtp
service running for outbound mail, and was never meant to accept inbond
mail for that domain. If Imail went to the MX records first, each time
this would not happen, but it appears that it is not happening since 6.04
or so. It is trying the default domain name first and not trying the MX
records. I'd like to see if any more people have noticed an increase in
Unknown User rejects coming back to their customers.
I have my IMGate box now handling all outbound mail from IMail, and the
problems have gone away. As soon as I put IMail doing the delivery the
unknown user rejects increase. I believe their is a correlation which
needs to looked into.
