[plug] Mail domain error

[Damion Hill]

I just recently went through the same issue with a server at work. 
The box was not listed in external DNS so a lookup of the server 
failed with the same error that you have shown.

On the Sendmail site I did some reading about masquerading and 
some of the options. I haven't got the config I used but look at 
http://www.sendmail.org/m4/masquerading.html
there are some options there that should help like 
masquerade_envelope. I think it is this feature that actually got me 
through.

Cheers,
Damion.
