[Mimedefang] mimedefang and milter-ahead

[George Roberts]

I'm using milter-ahead to call ahead to the recipient mail server to see if the receipient(s) of the message exist.  It appears that if milter-ahead rejects the message due to the user not existing on the recipient server that milter processing just ends ... what I really want to be able to do, if possible, is have mimedefang do some processing if milter-ahead rejects the message.  Essentially I want to increment a statistic for the recipient domain in a mysql database so I can keep track of how many messages were attempted to non-existent users for each domain.

Here' a log example:

Anyone have any idea if what I'm looking to do is possible?
