[nycbug-talk] Postfix filter for Exchange

[Francisco Reyes]

If I understood the original request.. it was about limiting mail bombs.

Mail bombs in theory could come from even the internal network.. caused by a 
rogue program (ie a bug in an alert).

One good program I once research, but have not implemented, is policyd for 
postfix. It seems like it may do what the original poster requested.

One can set limits so no more than X number of emails are received by 
conditions like sender, IP, and more.
