[Mimedefang] What is the order of things that occur

I believe that the mailertable is called by delivery agent when it delivers email. Mimedefang is running as a milter and should be called before email is relayed.

Subject: [Mimedefang] What is the order of things that  occur

I have just finished testing MimeDefang on a test gateway. All worked fine 
there. I apologize for making this task so bothersome on this list, but I 
now find that in production, it does do what I need. The following scenario 
exists.

I have two mailservers. Each server is the mailstore for a different domain. 
Each non-mailstore is a secondary MX for the other server's domain. Each 
secondary relays mail for the other server's domain using the mailertable.

I use a very simple mimedefang-milter. It just has the filter_recipient 
section in it and I use the md_check_against_smtp_server function in it to 
see if a valid user exists on the primary MX (mailstore) server.

Can someone verify for me that sendmail checks the mailertable and then 
relays before MimeDefang is called? All of the mail for the domain to be 
relayed is being "relayed" without MD doing any checks. Is there a solution 
to this?

This is how the setup here exists

mail to domain1 on server1 is local (primary MX for domain 1 also)
mail to domain1 on server2 is relayed to server1 (secondary MX for domain1)
MD running on server2 should check to see if mail to domain1 is valid

mail to domain2 on server2 is local (primary MX for domain 2 also)
mail to domain2 on server1 is relayed to server2 (secondary MX for domain2)
MD running on server1 should check to see if mail to domain2 is valid

Thanks
