The default configuration of Sendmail is set to relay mail from within the
server only.  If you set it to relay mail sent from any location, you have
what is known as an open relay.  POP before SMTP relaying provides you with
a controlled relaying machanism where users have to check mail first before
they are always to relay mail through your SMTP server.

When you check mail using POP3, the user's password is sent in clear text.
When you use APOP, the password is encrypted.  If you enable APOP for the
virtual site, it applies to all users of that site.  You may prefer to
enable it on a per-user basis.

You will need POP before SMTP if you want your external users to send mail
through your SMTP server.  You do not need all three settings.

>Also, can you have some sites witht the ip address set in relaying and
other sites using the APOP settings?

Relaying is about sending email while APOP is about the authentication used
to retrieve email.  You can set some sites within an IP address range to
relay.  This has nothing to do with the APOP settings.
