No debian neither dovecot problem.

protocols =  imap imaps
Be sure to have certificate for dovecot (Debian should create a default one)
ssl_cert_file = /etc/ssl/certs/dovecot.pem
ssl_key_file = /etc/ssl/private/dovecot.pem

I prefer to split up the pem file into crt and key and to use one of my
own certificates created with my CA, but you can also buy one... if you
like (verisign, thawte)
ssl_cert_file = /etc/ssl/certs/my_own_cert.crt
ssl_key_file = /etc/ssl/private/my_own_private.key
Check if the port does accept connection and if you can see the certificate:
openssl s_client -connect localhost:993 (imaps port)
That should do it.
