Hi *, I've noticed on my mail relays, that tls handshake with one certain email relay keep failing. I was wondering what the reason for that may be.
Following error from postfix: connect from mout.web.de[ IP ]:44003 SSL_accept error from mout.web.de[ IP ]:44003: -1 warning: TLS library problem: error:1404A42E:SSL routines:ST_ACCEPT:tlsv1 alert protocol version:/usr/src/lib/libssl/tls13_lib.c:150: lost connection after STARTTLS from mout.web.de Can anybody with more knowledge of libressl and it's error messages tell by this error what is wrong? Best regards, Stephan
