Re: force to use SSL port for delivery

We are actually using a customized version of Postfix, adding some 
features to support distributed systems. Yes I was talking about MTA to 
MTA communications, not MUA. We have hundreds of Postfix as MX cluster. 
The user number is huge, it's more than 500 millions IMO.
