Hello everyone,since i've updated openssl to 1.0.0 (first "b-r1" and "c" after) version i'm unable to establish TLS connection to some mailservers - probably with older binaries of openssl. Below is telnet connection with starttls to mailserver.prestice-mesto.cz - Kerio Mailserver 6.0.10. I found out that with never version of Kerio Mailserver TLS works. But today some other machines didn't work with TLS.
Anyone with same problem? Thanks Jan Hejlaq ~ # openssl s_client -starttls smtp -tls1 -crlf -tlsextdebug -connect mailserver.prestice-mesto.cz:25
