 External IMAP problems.
Hello,
Im trying to configure an external IMAP account. But is returning some strange errors (always worked).
The error of Zimbra is attached
And my IMAP server (dovecot) said me this:
Oct 6 16:49:34 observi dovecot: imap-login: Disconnected (no auth attempts): rip=192.0.0.2, lip=192.0.0.254, TLS handshaking: SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown
What can be that???
Please help!
regards
