Hello, the attached patch for Dovecot 2.2.4 improves the logging to include information about the cipher suite used for a TLS connection. Here is an example log line: Aug 13 21:49:55 colwyn dovecot: imap-login: Login: user=<tron>, method=CRAM-MD5, rip=2001:8b0:114:1::2, lip=2001:8b0:114:1::2, mpid=10567, TLS=<TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)>, session=<ZkEhYtrjSgAgAQiwARQAAQAAAAAAAAAC> This will e.g. allow you to find out that mobile phones use rather week cipher suites (128bit keys, no PFS). There is also something else...
