Although I'm no expert in qmail (still getting the feet wet
here), I am a network engineer. What this individual really
should do is go back to their ISP and ask for a fixed IP address
that isn't part of a dial-up users group. Trying to run a mail
server - ANY mail server - over a dialup IP is certain to lead
to headaches.
There are, however, other problems to consider. Many mail
servers do a reverse-DNS lookup to verify that the mail is
coming from an address that is a valid MX record. Without a
fixed IP address to bind to an MX record, this mail sysop is
headed for additional troubles.
