[Dovecot] Wishlist: TLS,SSL cipher in a variable.

Hello again.

Just thought I'd ask and see if it would be possible to get this sometime in the future: TLS and SSL connection information in a variable like %c today, but more exhaustive.

For example I can from postfix get a log like: postfix/smtpd[432]: Anonymous TLS connection established from xxxxxx: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)

This would be nice to see if you have a fairly low permissive level, to identify potential weak clients and be able to notify these to start with while still allowing connections.
