Normal inactivity timeout.

If I run it again and feed it an EHLO, I get back: 220 courieratwork.My.Do.Main ESMTP EHLO courieratwork.My.Do.Main 250-courieratwork.My.Do.Main Ok. 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN X-NETSCAPE-HAS-BUGS 250-XVERP=Courier 250-XEXDATA 250-XSECURITY=NONE,STARTTLS 250-PIPELINING 250-8BITMIME 250-SIZE 250 DSN My "esmtpd-ssl" file contains (at the moment)

This shows that the server is working correctly.

Yup. Did some more testing. It looks like "couriertls" listens on stdin after having read the certificate, apparently for the STARTTLS transaction to occur from the client end.

I configured Mac OS X's Mail.app to use port 465 with SSL and user authentication, and it worked just fine. Mail.app sends the appropriate response that "couriertls" reads (I think it begins with "80", and then something that's presumably SSL encrypted), and it's off to the races from there.

Entourage 2004, on the other hand, sits there like a bump on a log. So of course "couriertls" times out eventually, because Entourage never talks to it. Apparently if you override port 25 in Entourage with a "Use SSL" and "use authentication" setting in your outgoing SMTP server setup, it loses its marbles and doesn't know what to do.

Chalking this up to Entourage brain-damage. Sorry for the noise.

Thanks Sam,
