IF MF had anything that could do TLS certificate verification, it would
be in their Secure Messaging Gateway product (aka GWAVA 7).  Based on
how MF handled DKIM implementation in GroupWise, my guess is going
forward all email security is going to be built into SMG with MF wanting
you to put GWIA behind SMG.

Hi Marvin,

I’m pretty sure that GW cannot do this. Unless MF has a better
workaround, I’d punt and use a Postfix front-end, which can require
certificate verification, at least from their doc statements.

or has it ever had this capability. It just uses whatever certificate is
presented without verification, which is why it works fine with self
signed certs.    And furthermore, I've never in my career seen an email
server that requires certificate verification befor.
