That is correct, this combination of software works very well on eCS 1.2r but not on any eCS 2.0 version. It's possible to sign mails but if you encrypt them sending will result in a mail server time-out. A message comes up telling you that the server is not available with (#4.4.2), and that message doesn't help me at all?
There is nothing wrong with the mail server of cource, it works when using 1.2r? I have not been able to solve this. It should be very negative for eCS 2.0 if it's not fixed before release. I have not received any useful help so far. If I can't use eCS for mailing it will be difficult to use it at all in the future.

BTW. Thanks for a great article!
