My employer uses Tumbleweed. Be careful on how you setup the triggers
for securing e-mails. I have sent innocuous e-mails that our policies
flagged as requiring security (including to this list, hence the "not
secure" addition to the subject line!). Yet I can send an e-mail with
the phrase "the root password to the Solaris server is makemydaygeek"
and it would sail through...  Not Tumbleweed's fault, it's the arcane
policies we have setup...

I have a client that uses Tumbleweed to send secure emails. It works at
the email server level (these folks use Exchange), intercepting any
email message with the string ##SECURE in the subject. It then sends an
email to the recipient telling them they have a secure email waiting for
them at the client site; they need to connect to the site (via https by
clicking a link) and  authenticate themselves (or if first time create a
user & password), then they can view the text + attachments of the
original email. Works seamlessly with outlook+exchange and with
automatically generated emails from the UV/Linux system that use SMTP to
connect to the exchange server.
Should also work with other email clients. Not cheap, but pretty cool.

Another option would be pgp/gpg if full paranoia mode is required.
