[NTLUG:Discuss] Sendmail question

[Joe Torma]

I'm a newbie so please go easy on me...  Recently downloaded, burned and
installed a copy of RH 7.3 on a Dell PowerEdge 4200 server.  I am wanting
this box to handle email for a domain hosted elsewhere
(http://www.richardsonhumanesociety.com).  Is this possible?  If so, for
someone who knows nothing about sendmail and very little about Linux (or any
other Unix-like environment), how difficult is the challenge?  What I would
like to do is be able to assign user mail accounts which members can check
through their respective email clients if possible.  If we can tackle this
one I would also like to talk about the feasibility of hosting FrontPage
webs on Apache, and / or using the Linux box as a point of origin for .asp
pages for a web which is hosted elsewhere, if possible.

Info:
RH 7.3 SMP core (2x333Mhz) configured as server without customization or
additional package installation.
Have DSL and Static IP's
Have multiple Nic's in the server
Have Linksys 4 port router (Would probably need another if more than 1 Nic
from the server needs access.)
More info available if needed.

Thanks in advance.
