Thanks for all the replies... I don't actually need to worry about "port number" -- 465 or 587... as long as the user has authenticated, that's what I'm chasing after.
For Steffen, I'm looking in /etc/mail/mimedefang-filter and don't see filter_recipient or filter_sender. (I'm on mimedefang 2.74 as packaged up on EPEL running on CentOS) So to all (Like Joseph) , it looks like I can add this to filter_end near/at the top -- returning the ACCEPT_AND_NO_MORE_FILTERING as described in the following emails. Yes? Thanks, -Ben _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID. You may ignore it.
