1. Install and run sendmail if it isn't already. (If you don't
want to use sendmail for whatever reason, you're on your
own.)
2. In the file /etc/sendmail.cw, put one line for every domain
your machine will accept mail for, e.g.:
# sendmail.cw - include all aliases for your machine here.
domain.com
3. Create a sendmail.mc file such as (substituting domain.com):
include(`../m4/cf.m4')
define(`confDEF_USER_ID',``8:12'')
OSTYPE(`linux')
MASQUERADE_AS(domain.com)
MASQUERADE_DOMAIN(domain.com)
undefine(`UUCP_RELAY')
undefine(`BITNET_RELAY')
define(`confAUTO_REBUILD')
define(`confTO_CONNECT', `1m')
define(`confTRY_NULL_MX_LIST',true)
define(`confDONT_PROBE_INTERFACES',true)
define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail')
FEATURE(`access_db')
FEATURE(`always_add_domain')
FEATURE(`local_procmail')
FEATURE(`masquerade_envelope')
FEATURE(`relay_entire_domain')
FEATURE(`smrsh',`/usr/sbin/smrsh')
FEATURE(`use_cw_file')
FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable')
MAILER(procmail)
MAILER(smtp)
4. Generate a .cf file from a .mc file saving the original. As
root:
cd /etc
cp sendmail.cf sendmail.cf-orig
cd /usr/lib/sendmail-cf/cf
m4 sendmail.mc > /etc/sendmail.cf
5. Send a HUP signal to the sendmail process.
6. If you have any kind of firewall, you need to allow port 25.
You should be good to go. You need the masquerading stuff
above only if you want to be able to use your mail machine to
relay mail for any machine on your internal LAN if you have
one.

I personally don't like POP mail, but: install and run qpopper.
(You get it free from Quallcomm.) Read the docs: it's fairly
straightforward.
