Dear list, I have followed Rudy's Suggestion and TLS is working. I have run *imtest -t "" linux.kolkatainfoservices.in* and following is the result S: * OK linux.kolkatainfoservices.in Cyrus IMAP4 v2.2.12 server ready C: C01 CAPABILITY S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE IDLE STARTTLS X-NETSCAPE S: C01 OK Completed C: S01 STARTTLS S: S01 OK Begin TLS negotiation now verify error:num=19:self signed certificate in certificate chain verify error:num=24:invalid CA certificate verify error:num=26:unsupported certificate purpose TLS connection established: TLSv1 with cipher AES256-SHA (256/256 bits) C: C01 CAPABILITY S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE IDLE AUTH=LOGIN AUTH=PLAIN SASL-IR X-NETSCAPE S: C01 OK Completed C: A01 AUTHENTICATE LOGIN S: + VXNlcm5hbWU6 Please enter your password: C: cm9vdA== S: + UGFzc3dvcmQ6 C: a29sa2F0YQ== S: A01 OK Success (tls protection) Authenticated. Security strength factor: 256 But from the above you can see the problem with self signed certificate. So how can I still work with self signed CA ? thanks ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
