Yup. I used to do that, but had an older version of sendmail and got
'co-opted' as a relay host for a spammer. :-( But the Linux distribution
included a pop3 server out of the box, and my Windows machines were able to
connect to it just fine.
FWIW: rather than update sendmail and hack another .cf, I bought a
Windows-based mail server from a company called True North Software
(www.tnsoft.com) and I'm running it on Windows 2000. It also provides a
POP3 server that the other machines access (so my family can have email,
too), and is a complete no-brainer to administer. Once upon a time I
thought it was fun to administer a mail server; now I really appreciate this
'hands-off' solution. :-) OK, I paid $150 for a piece of software, but
when I consider the value (to me) of my free time, that's chump change....
Instead, I use my free time to hack 2.11BSD and UNIX v6! :-) Cheers -- Ian

In case the above seems stupid the idea is to
take all email through
a
server, weed out all incoming rubbish, and route
it to various
individual's (partner, daughter etc.) PCs.
This is exactly what I do, though I have the sending and receiving
sides of the email equation separate. I have one machine that acts as
a mail hub. It runs sendmail with a custom sendmail.cf which is
capable of delivering internal mail either to /var/mail, which is then
exported to other machines, or via UUCP or SMTP to other machines. It
also batches up outgoing mail and sends it to my ISP's mail server
("Smart Host") at specific times of the day (mine's not an always-on
connection).
All the other machines either use UUCP, or use sendmail with the
"nullclient" .cf file, to send mail to my hub machine. No reason why
the hub couldn't run a POP3 server for the benefit of Windoze PCs as
well, but I've never felt the need :-) If you go that route, I'd
suggest you think about IMAP rather than POP, though. As far as
getting mail from my ISP, I use fetchmail -- but if you do this, be
sure that your ISP puts something in the headers that makes it easy for
fetchmail to tell which user it's really for (don't forget about
mailing lists), and that you have a catchall rule to handle mail you
didn't think of.
If you have an always-on connection, you could have your DNS MX
record(s) set to point to your hub machine, and needn't use fetchmail.
However, if you do that, be sure to set up sendmail with anti-relaying
and all the proper security patches.
