$ grep imaps /etc/inetd.conf

If you already have inetd listening on that port, perhaps you already
have a functioning IMAPS server, and don't need stunnel at all.  What
do you get when you

  $ openssl s_client -connect localhost:993

If it looks like imap with lots of SSL handshake first, then you've
already got IMAPS.  Pat yourself on the back and call it a day .

Else, you can remove the entry from /etc/inetd.conf and HUP inetd,
and then your stunnel should be able to bind port 993.

It is also possible you don't have the imap server listening on
port 143 (cleartext) at all.  Again, 'grep imap /etc/inetd.conf'
to see what it has.  You can use exec in stunnel if you don't
already have imap listening on 143.
