Hello, On F8, the mechanisms in cyrus-imapd using sasl haven been changed from plaintext to plaintext+tls (default). I upgraded now to F9 - now it again doesn't work. Looking in the logs, i found some small differences: Before Upgrade: plaintext+tls After Upgrade: plaintext and this, even if the logs are showing the tls-handshake before. Is anybody aware of a change of the authentication to cyrus using sasl beteween F8 and F9? Now, i changed temporarly to digest-md5 using sasldb. Any ideas? Roger
