I believe that the special form of a S/MIME email can be easily intercepted by the mailscanner engine, so a future work
could be this feature, but the responsiveness to the real world attack (mailscanner do this form me...) is a crucial
point in computer security; maybe if mailscanner will be sold out for 30.000 $ to these companies, Julian will be happy
and the company too (they think that Opensource is worst, and payware is better .....)

MS is definitely the better way to do this job. (... if Julian support us for 30 years from now ...)
