If you're referring to ssmail, the D-H exchange is done at the sendmail
conversation level, and by far the most common case is that mail goes from
the user's machine to the corporate mail gateway machine, which establishes
a TCP link to the recipient's gateway, which forwards to the destination
machine. The first and last of those are presumed to be behind firewalls,
and the long haul is encrypted only once. If the long-distance connection
can't be established, the mail will go to an alternate MX holder instead.
If you don't trust your own MX holders, you have other problems.
Greg.
