[fetchmail]Rejecting large messages when using "sendmail" for delivery

It doesn't mention that "the local MDA mode is half-baked" in the man 
pages...

Seemed like a good solution to me because the point was I wanted a way 
to bypass all my usual postfix restrictions.  Situation is that I 
normally reject mail which looks "suspicious" like having an email 
address which is obviously fake.  At least this way someone might get a 
bounce or failure message if it's really genuine.  However, by the time 
fetchmail is handling mail it's going to become a bounce, so I am in the 
awkward position of effectively silently discarding users' mail (because 
the orig email address appears to be fake or at least it's unreplyable).

I can work around this by setting up multiple instances of the smtpd I 
guess, but I was hoping to work around it in the simple way I just 
described.

Also, since changing back to using the SMTP delivery option I get 
occasional points where fetchmail dies with "terminated with signal 
13".  I'm going to set it up under daemontools if I can figure out the 
correct fetchmail incantations...
