[CS-FSLUG] Sendmail with multiple domains

[Doug Coats]

Can someone please a few moments of your time and help resolve a problem for
me.

I am trying to get Sendmail to work with multiple domains.  I have had
Sendmail working properly for a number of months with one domain but now I
have been asked by a friend to add email and web hosting for their domain.

I have tried a number of things with the same result - Sendmail denies
relaying for the second domain.  All mail is returned to sender.

So if someone has this working on your machine and can explain it to me step
by step so that I can figure out where I went wrong or which step I missed
that would be great.

Thanks,

Doug
