Here's an update on this issue.  I forgot to mention earlier than the 
system is FreeBSD 6.2 p8.

The problem seems to be specific to imapd-ssl running on port 993.  I 
didn't spend a lot of time troubleshooting different clients.  Previous 
to the update, I used Thunderbird with SSL/port 993 without problems. 
Strangely, Korn (KDE mail notifier) seemed to work okay on port 993.  It 
could be a client thing but I suspect they just default to different SSL 

TLS works just fine on port 143, which is the configuration I've been 
meaning to switch to for some time.  The update forced the issue and 
thus, this problem is not really one anymore.  But for those who are 
still using imaps on port 993, the update (either the courier-imap 
update or the SSL update) may cause some problems.
