If you're on dial-up, perhaps qmail (and other "real" MTAs) are not the
best solution. You may want to consider a relay-only MTA like
nullmailer.

ISP smart relays do not require SMTP-after-POP authentication from addresses
they control (their dialup pools, etc). If they did, 80% of their
customers would be unable to send mail properly, and they'd fix it right
quick.
The right solution here is always use your ISP's smarthost. That's what it's
for, and it will keep your mail from being marked as spam, refused, or outright
dropped on the floor by those servers which consult the DUL.

If you decide to use qmail, then have a script which executes when you connect
to an ISP which does the following:
-`echo ":1.2.3.4" >/var/qmail/control/smtproutes
-start qmail
and another which automatically stops qmail when you disconnect from the ISP.
Replace 1.2.3.4 with the IP address of the ISP's smarthost. This will cause
all your remote deliveries to be relayed through the ISP's smarthost.
