This message is crossposted to the Postfix users list and the OpenSSL users list. Hi out there! by looking for a good way to allow mail relaying for our roaming users, I had the idea to use TLS with Netscape and client certificates. Of course, it turned out more difficult than expected, as it is not enough to just run "sslwrap" or "stunnel" around the SMTP port. It was necessary to implement (parts of) RFC 2487. After digging around a little bit I found postfix to be the best readable and extendable source code, so I decided to use postfix as a base and write a patchkit using the OpenSSL library I have now a working (at least for me :-) version ready and want to invite other people to participate in the development and test (and/or just use) my enhancement. You can access the software from our website http://www.aet.tu-cottbus.de/personen/jaenicke/pfixtls/ The outfit is a little bit raw as of now, but that may improve in the future :-) Of course, I would like to hear your comments and bug reports or even better bug fixes...
