Thank you ReetP
i understand you wont support 9.2 anymore but i need 1-2 weeks time to setup a new server with hardware.
that i found in the logs:
imap-login: Info: Disconnected (no auth attempts): rip=X.194.X.93, lip=192.168.x.x, TLS handshaking: SSL_accept() failed: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher
Will this maybe fix the issue until i have a new computer to setup V10 ?
ssl_protocols = !SSLv3
ssl_cipher_list = ALL:!ADH:!LOW:!EXP:!aNULL:+HIGH:+MEDIUM
at the moment i have: HIGH:!SSLv2:!ADH:!aNULL:!MD5:!RC4
