Foiled by my "Reply-To", sorry about that.

> Viktor, please stop using the exim-users mailing list for advocacy.


Apologies if the above can be read that way. No advocacy intended,
scout's honour! I thought I was saying that the feature the OP
claimed exists in Postfix, and was looking for in Exim, also does
not exist in Postfix. So hardly intended as a Postfix advertisement,
but perhaps TMI can look like advocacy, sorry about that.

I'm only here to learn about any issues that affect both MTAs,
particularly in the TLS space, and where it seems appropriate to
occasionaly share TLS experience learned by the Postfix community
that might also be of value here.
