Hi I have configured one line in postfix main.cf (after configure each line I check /var/log/mail.err): smtpd_tls_dh1024_param_file = /etc/postfix/dh2048.pem
After setup above line I have error in above log file (these 4 lines looped): Apr 25 14:08:09 serwer-1 dovecot: imap-login: Error: SSL: Stacked error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol Apr 25 14:08:09 serwer-1 dovecot: imap-login: Error: SSL: Stacked error: error:1408A10B:SSL routines:ssl3_get_client_hello:wrong version number Apr 25 14:08:51 serwer-1 dovecot: imap-login: Error: SSL: Stacked error: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac Apr 25 14:08:51 serwer-1 dovecot: imap-login: Error: SSL: Stacked error: error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher Apr 25 14:14:25 serwer-1 dovecot: pop3-login: Error: SSL: Stacked error: error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher Apr 25 14:10:51 serwer-1 dovecot: pop3-login: Error: SSL: Stacked error: error:14094085:SSL routines:ssl3_read_bytes:ccs received early Apr 25 14:09:16 serwer-1 dovecot: imap-login: Error: SSL: Stacked error: error:1408A0E3:SSL routines:ssl3_get_client_hello:parse tlsext
And second thing: smtpd_sasl_security_options=noanonymous,noplaintext smtpd_sasl_tls_security_options=noanonymous,noplaintext These two lines in main.cf postfix file generate error no SASL authentication method.
What should be configured in Dovecot to avoid both problems?
