This possibility cannot be completely ruled out...
However, the point is that with Sendmail+milter, you do notice crashes,
because milter runs as a single multithreaded process and when it
faults, no further mail is accepted at all.  Possibly, in other setups
(with Zmailer for sure), when a process that is trying to accept a
problematic message crashes, this is not a cause to worry...
