If "-b" is set to define a spambucket, and "-i 127.0.0.1" is not set,
and "-r" is set, rejected spam may loop in sendmail until the loop
counter overflows (21 ?).
Although setting "-i 127.0.0.1" seems to solve the looping problem, some
mail setups may wish to filter outgoing mail (webmail interface on the
same server) or preprocess so that all mail comes via localhost.
The following patch forces mail sent to the spambucket as the only
recipient to be accepted:

+ }
if (assassin->numrcpt() == 0)
I had to set '-b <[EMAIL PROTECTED]>' rather than just
'-b spambucket' for this to work.
