Mail handler. It is a type of DNS record. There are "A" records and
"MX" records (and others I am sure). It allows you to have a domain
name that has a certain IP for handling general requests (ping, http,
ssh, etc) and a different one for handling mail (SMTP).

What you need to do is set your outgoing address to be the one from
your ISP. When you are sending mail, pine hands of responsibility to
exim (via a pipe), right? exim then tries to transfer (via SMTP) to
the host it is configured to send to. Try adding your local username
(doesn't have to match your ISP, btw) and your ISP-given email address

Yeah, you are reporting yourself as "shyamk@localhost" (note the
Return-Path:, Received:, and Diagnostic-Code: lines) but the MTA on
the other machine rejects that because it is not a real address (that
it can route messages to). It thinks you are a spammer spoofing your
return address. Adding the line to /etc/email-addresses will rewrite
your information (I think just the envelope-sender part, not the From:
header) so that your "real" (publicly visible) address is given.
Also, in pine be sure and add your domain to the From: header! If you
do this, you may not need to edit /etc/email-addresses, or if you do
edit that file you may not need to correct pine's setting.
