POP before SMTP

[Brian Witowski]

Be careful how you set it up.  If you want it to sign your messages with a
particular domain, keep in mind if it is NOT a valid, registered domain,
like mine isn't, and the recipient does a reply, it will get bounced.  When
email is sent, the DNS servers look at the domain portion and ignore the
username portion.  It then does the equivalent of an nslookup with type set
to MX to find the recipient mail server.  Your domain needs to be registered
with appropriate MX and ETRN records.

In my case, I send using my own sendmail, but for receiving I use fetchmail.
In addition, for internal email addresses I use Address Mapping (virtuser).
This redirects specific email addresses to internal POP3 linux accounts, so
it never leaves my network.
