OK let's ignore the mail server portion. Your basically implying
that encrypted mail handling from the server, does not matter if
it's an exchange server, or *nix, like postfix....

As an example.
Look at the situation where a person is using only MS technology
and has no access to support(input) on their client software nor the
MS exchange server (big corp for example that assumes the world
only uses MS software). Maybe they can make a few setting changes
only in Outlook to get encryption working between a MS (Outlook)
system and my Gentoo system using pgp and thunderbird?

I do not have a problem. I have assumed that encrypted mail between
a given client software on a gentoo system, will not work with windows.
Is this assumption incorrect?

Or it's just install whatever I want (mail client on gentoo) and it wil= l
auto-magically exchange encrypted mail with outlook on =A0a windows machine= ,
behind a MS Exchange server, regardless of what the MS admins
do on their side?

I assumed that is not that easy (my default experience with MS),
and things have to be coordinated, like most MS issues, to be
able to exchange encrypted mail between a gentoo and MS workstation....

Nothing to it, or massive issues on the MS side? Obviously,
making changes on the gentoo workstation client, is easy....
What I would really like is to be able to exchange encrypted mail
with any MS user. =A0That, I'm sure with entail pointing them to
documents on how to set up the software on the MS (outlook) side.
Links for MS help?

???
A general discussion at this point, not a specific solution.
My googling only reveals dated discussions along these lines
or information that is not useful.
