I believe, if you're using fetchmail, and your MUA sends email
by piping into /usr/{sbin,lib}/sendmail (as mutt does), that you
may be able to disable smtpd entirely. Easy check: grep smtpd
/var/log/maillog, that'll tell you if it's doing anything. If not,
then # out the smtpd line in /etc/postfix/master.cf and restart
postfix. Check your work with "lsof -i -n".

If your smtpd is seeing work, it may be because of your MUA
(Pine seems to insist on sending into a local SMTP port, and
is semi-broken at it what's worse, very fragile anyway, hangs
mysteriously). If that's the problem, you need to figure out a way
to convince the MUA to pipe into sendmail like it's supposed to, or
else switch to a competently written MUA.

If however fetchmail is your problem, that should be _easy_ to fix.
I'm very happy using

        mda "/usr/bin/procmail -t"

in my ~/.fetchmailrc. If you want Postfix to do its own direct local
delivery, that should be easy with

        mda "/usr/sbin/sendmail"

(substituting the right path for the sendmail program on your
system, often /usr/lib/sendmail).
