Postfix and Unitywave: Need POP-before-SMTP

[William Lindley]

Pluggers,

I've signed onto Unitywave's dialup.

They require you to login to their POP server before sending SMTP mail.

I've found LOTS of info (on Google et al) about how to set up a Postfix
*server* to require POP-before-SMTP...

BUT NOWHERE is the answer to:

 * How do I set Postfix to login to SMTP before sending mail?

Because unless I run fetchmail every five minutes or so (which is a pain,
I have to shut it off and turn it on unless I want the modem online 24/7)
all I get every time my system decides to send mail is:

   Relay access denied

Hoping y'all can help,
