Hello again I've configured my Cyrus 2.0.16 to work with SSL/TLS as the docs included on the package says. When I do: imtest -t "" imaptest.unrc.edu.ar i get the following: C: C01 CAPABILITY S: * OK test Cyrus IMAP4 v2.0.16 server ready S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT MULTIAPPEND SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES IDLE STARTTLS AUTH=DIGEST-MD5 AUTH=CRAM-MD5 S: C01 OK Completed S01 OK Begin TLS negotiation now verify error:num=18:self signed certificate TLS connection established: TLSv1 with cipher DES-CBC3-SHA (168/168 bits) C: C01 CAPABILITY S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT MULTIAPPEND SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES IDLE STARTTLS AUTH=PLAIN AUTH=DIGEST-MD5 AUTH=CRAM-MD5 S: C01 OK Completed Please enter your password: C: A01 AUTHENTICATE PLAIN S: + C: S: A01 NO bad protocol / cancel Authentication failed. generic failure Security strength factor: 0 . logout * BYE LOGOUT received . OK Completed Connection closed. What is this "verify error:num=18:self signed certificate" message and why this "S: A01 NO bad protocol / cancel Authentication failed. generic failure" shows? If I configure the Netscape 4 client to use the secure connection it works ok.

The last is the connection from the Netscape client. Any comments?, Do I have a configuration problem?
