From memory - we do use the things, but standing instructions are to
switch off SMTP f**up features - this is basically the case.
Additionally the initial SMTP banner (ie 220 hostname ....) has large
chunks ****'d out so many systems won't try ESMTP since the ESMTP
part of the banner has been removed.

Either of those work well. ASAs do suffer similar issues. Unfortunately
I can't get at one to test against at the moment.
