Cyrus not listenting to port 993?

[Daniel R.]

I am trying to get IMAP over SSL to work and am running into a real puzzle.
Every time I try and connect to port 993 I get no response at all.  It 
seems that Cyrus master is not listening to port 993, even though it 
says it is.  It is listening on port 110 and 143 though.

The key parts of my config and log files are listed below.
Thank you for your help.
