Well the symptom is that the OS X mail client just times out. It talks to port 993 on the server for a while, but just shows the user a moving icon. Eventually it complains the mail server didn't respond. 10.3 and 10.4 work fine, strangely enough. It times out as it's "checking connection to the mail server."
I did upgrade from dovecot 1.0 to 1.1 without doing much of any config changes on the dovecot side. But other clients work fine...
Actually I just realized while watching tcpdump that Mail.app is testing port 25 after 993. So it may be a Postfix SSL failure of some sort.

People using the new OS X mail client are unable to connect to the unsigned dovecot-mkcert.sh certificate on my Dovecot installations. Turning off SSL fixes the problem. Is there any way to make it work automatically, or do I just have to get the certificates signed? Has anyone figured this one out before?
I have an unsigned SSL certificate with Dovecot and connect fine using OSX.5's Mail.app. What do you mean, "unable to connect"? Do you really mean "unable to connect", or do you mean, "an error message comes up every time they try to connect"?
If its the latter complaint, please see this document: http://support.apple.com/kb/TA22383
I know it says 10.3 Mail, but the steps to follow are essentially unchanged between 10.3 and 10.5.
