closed SMTP channel - response overrun on smtpwrite()

[Eugene Crosser <crosser@online.ru>]

I am getting reproducible problems with a particular host.  They are
getting from me the same message numerous times.  And this is what I see:

It *looks* like the Chekpoint FireWall-1 (that is known to be buggy in
other aspects) start sending lots of junk instead of "221".  But to be
sure - did anybody notice similar things and/or has ideas?
