qmail


gnupg


the fact that you are looking for a "secure e-mail server" indicates
a certain ignorance, as SMTP protocol at this time specifies that
the message stream is not encrypted, making it susceptible to 
"packet sniffing."

This vulnerability can be overcome by encrypting the message using a 
tool such as the GNU Privacy Guard (largely based on the work of a
certain Phil Zimmerman).

There is not at this time a standard for encrypting the entire channel
between mail servers, and it is unlikely that one will appear.  When
there is risk of people reading the traffic that goes by, a better
solution is to encrypt the entire network into a "virtual private
network."

For use internal to your organization, encryption of the smtp stream
can be added to any open source MTA without great difficulty.
