Set up the "receiving" side of a content filter on, say, port 10025, and
redirect fetchmail there. OTOH, usually 127.0.0.1 would be in Postfix's
mynetworks, and "permit_mynetworks" early in the restrictions, or
restrictions that don't apply to 127.0.0.1, would fix your problem while
still using the SMTP port (BTW, Postfix's SMTP port is faster than
Postfix's sendmail interface).

That is something you cannot fix with any setup, and you can IIRC defeat
bounces altogether.

daemontools isn't going to help, and buys you into proprietary,
time-limited software. A free (GPL or something) and halfway compatible
replacement is "runit", somewhere on http://smarden.org/
