[NBLUG/talk] Sendmail

Hi everyone,

Sendmail noob here!! I've got a colo box at sonic that I run some 
websites from. One of the sites (co.dsm.org) has a majordomo mailing 
list attached to it and is working fine. The problem is when the list 
admin logs on to the machine and tries to send mail *from* it. The from 
address appears as "user at sonic-1u.sonic.net" instead of "user at co.dsm.org".

This causes most of his mail to be returned with: "some.isp.com requires 
a valid sender domain" Anyway, I've googled alot and played with 
sendmails Domain Masquerading, Outgoing Addresses(genericstable) and 
Outgoing Domains stuff to no avail. Does anyone have any insight on 
probably the very stupid thing I'm doing wrong?

Sendmail version 8.12.11
Mandrake 10

Thanks,
Mark
