You can try Djigzo (http://www.djigzo.com/). It's an open source email
encryption gateway with support for S/MIME and PDF encryption (with
support for random generated passwords via SMS gateway).
You can install it on your own system (.tar and .deb files available) or
you can use the provided VMware virtual appliance.
By default it uses Postfix for the delivery of email and it's therefore
easy to integrate with your existing Postfix solution (for example
combine it with an existing virus scanner).
More information available on www.djigzo.com

After a little guidance on what those of you using Postfix as a gateway
are using for doing s/mime email encryption?
I did some digging and it seems you can get certificates that
authenticate a company for s/mime rather than needing to authenticate
each individual using a cert on their MUA.
Of course Postfix can't do this, but I'm hoping I can get some
suggestions on what can, and (importantly) what integrates easily with
Postfix?
Thanks,
Paul
