The issue was that sendmail thought it didn't need to change the  
domain because the server was a host inside the domain, that didn't  
help however since there is no DNS mapping to the server in the real  
world, just to the base domain.

So I have user at server.domain.com and I want sendmail to change it to user at domain.com 
, I tested it by changing the server to server.test.com and sendmail  
then happily mapped out going mail to domain.com. So any ideas on how  
I can get it to drop the sub-domain on the out going mail? I tried  
putting FEATURE(masquerade_entire_domain) but this had no effect. I  
also tried specifically specifying  
MASQUERADE_DOMAIN(`server.domain.com'), however this also didn't do  
anything.

Shouldn't this be fairly simple to achieve?
