Greg,

You may want to take a look at sendmail's "DoubleBounceAddress" option, 
which lets you route double bounces (errors reporting errors) to e-mail 
addresses other than postmaster.  IIRC, there was a posting on the 
ISP-Linux list recently about routing double bounces to /dev/null.

I haven't played with this myself.  It's on my to-do list.

Of course, this doesn't stop your server attempting to report the error 
for five days.

Regards,

	Richard.
