But doing it in dovecot would mean that it wouldn't matter what MTA you 
were using, or even what OS/platform said MTAs were running on, you 
would handle all said policies for your entire (dovecot-director) 
infrastructure in one place (dovecot)...

Also, this would only be for *outbound* policies, so would provide a 
degree of separation with your *inbound* policies... which could be a 
good or bad thing I guess depending on your needs and requirements.

Like I said, I haven't thought it completely through and it may indeed 
be a bad idea...
