We have a uVAX II running BSD UUCP (we have a source license), and things
mostly run fine, but I'm curious about a few things.
1) When uucico is running through a list of sites, and one the sites
   fails in the middle of a converstion, uucico will call all of the
   succeeding sites, but then fail at STARTUP.  Does anyone have a fix
   for this?
2) The neat little feature of being able to toggle debugging by sending
   a SIGFPE to uucico is great *except* that for some reason, our uucico
   gets a SIGFPE in the middle of some calculation and then toggles 
   debugging about 500 times before going on.  I've changed the debugging
   signal to SIGUSR2, but does anyone have any suggestions on how to
   figure out where the floating point exception is occurring?  It doesn't
   occur on a regular basis, and I can't duplicate it when I run uucico
   by hand.
3) Is there any way to return mail back to the sender if he doesn't
   have an account on the machine?  The -m flag to uuclean will send mail
   to the owner of a file when it deletes it, but what if the file is
   owned by uucp because it was sent by someone on another machine?

Thanks,
