What I meant by this is if I have two domains (domain1.com and domain2.com)
and a user (user1)  what is stopping me from sending email to
user1@domain1.com and user1@domain2.com when I only want user1@domain1.com
to work.  And what id I have two user1 usernames for each domain.

After doing a little bit of reading I think this is all solved through
aliases.  Correct?

I plan to set this email server up for someone that has little to no
knowledge of linux.  I would like to set it up and be done with it.  But it
needs to be easy to maintian so one can add/delete users when needed.

I am in a position to install whatever is best.  At this point I am just
using what comes with RH8.0.  But I am very much interested in any feed
back.


Thank you
