我試圖在993端口上連接dovecot,但dovecot顯示下面的錯誤;如何在993端口上使用squirrelmail連接dovecot
dovecot: imap-login: Disconnected (no auth attempts in 60 secs): user=<>, rip=192.***.***.***, lip=192.***.***.***, TLS handshaking: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol, session=<3k6jgTwVLwDAqL+E>
squirrelmail config;
$imap_auth_mech = 'login';
$use_imap_tls = 1;
$imapServerAddress = 'dovecot.server';
$imapPort = 993;
當我嘗試在squirrelmail服務器上telnet和openssl時,
[[email protected] ~]# telnet dovecot.server 993
Trying 192.***.***.***...
Connected to dovecot.server.
Escape character is '^]'.
[[email protected] ~]# openssl s_client -connect dovecot.server:993
...

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
注: 143端口的方式工作正常。
