Sorry Alexis, but you're just plain wrong.  You must have never suffered a
security incident, or you would know that absolutely *nothing* is worse.  A
bad security incident can put a company out of business in seconds.
Otherwise, it will still take much more work to recover from a security
incident than a core dump in your mail system.

If nothing else, those naughty child monkey-see-monkey-do "crackers" are
usually more malicious than any programming error in ZMAILER.  :-)

I think Matti's priority list is correct, though I would list "does it cause
misbehavior without a memory fault?" before "does it cause core-drops ?"
since they can be much harder to spot/debug.

If core dumps worry you more than security, just send us all your root
password and we'll check your $POSTOFFICE directory for core dumps once in a
while. :-) :-) :-)
