Mail to postmaster

[Adi Linden <adil () adis on ca>]

I am looking for insight on how to handle mail addressed to postmaster. I 
guess a human being is supposed to read these? Some months ago mail to 
postmaster went from nearly zero to 10,000 a day in a very short time 
(hours). Ever since then postmaster email has been filed in /dev/null. 
These days we're still at about 2000 postmaster emails per day. Anyone has 
any sensible ideas of how to process mail to postmaster so only relevant 
stuff is forwarded to a human being?
