I assume the ISP you are getting your dialup connectivity from is not
the same ISP you are getting your SMTP relay from - otherwise, they
should let you relay from their IP addresses. And I assume the ISP that
you are dialing from does not provide a reliable relay?
POP-before-SMTP is really a client-oriented setup for relay auth. If
you are running a mailserver, you should look into using AUTH-SMTP, or
get a static IP and get them to let you relay from that IP. (Or maybe
with the static IP, you can send directly) An intermittent/dynamic IP
connection is also really a designed to be used by individual clients -
a mailserver really should have better connectivity.
