Re: Mail relaying on postfix using the Jamm environemnt

Hi Buzz
Take a look at POP-BEFORE-SMTP Mailserver for mobile users with Postfix
You find it at
http://www.stahl.bau.tu-bs.de/~hildeb/postfix/postfix_pop-before-smtp_en.shtml

Some cut and past from the page
POP/IMAP-before-SMTP authorization:
The user must authenticate himself from the SAME IP he'll later use to
send his email from. This is only possible during a small timewindow after
the POP or IMAP authentication. SMTP-AUTH: The most elegant method. During
the SMTP Dialogue, the sending machine specifies username and password. If
this authentication is successful, relaying will be permitted.
