I haven't had such an assertion made to me, but then, I am not an NHS 
employee.  I would be surprised though if their secure mail solution 
involved you sending via TLS from their internet facing (MX record 
target) server, rather than (eg) using RPC-over-HTTPS with 
outlook/exchange, some sort of delivered app (such as a citrix 
environment), or https webmail.

Wouldn't surprise me, either way. As an external company merely sending 
email to NHSnet users, we couldn't even raise it is a ticket - we aren't 
users of the mail system (other than sending mail to those who are, 
obviously)
