Fixed ! This is an openssl issue : latest upgrade force "MinProtocol = TLSv1.2" in /etc/ssl/openssl.cnf Looks not compatible with the company Exchange server... I fallback to "MinProtocol = TLSv1.0" and mailnag is now happy.
Hello, Since last update of my Debian testing, mailnag stop working with the following error :
ERROR (2018-12-14 11:12:22): Failed to connect to account 'Exchange' ([SSL: UNSUPPORTED_PROTOCOL] unsupported protocol (_ssl.c:727)).
I have only one IMAP account (on an Exchange server).
A tshark capture seems to points a protocol version error :
10.7.1.135 > 10.1.1.30 TLSv1 583 Client Hello 10.1.1.30 > 10.7.1.135 TLSv1 567 Server Hello, Certificate, Server Key Exchange, Server Hello Done 10.7.1.135 > 10.1.1.30 TLSv1 73 Alert (Level: Fatal, Description: Protocol Version)
Same alert with TLS (no SSL)
Can you help ? Thanks. Phil
