That should be the correct way, but I think there shouldn't be a space after the < character. What exactly is the error you are getting?
You can troubleshoot with openssl s_client, this is from my server: $ openssl s_client -connect 192.168.xxx.xxx:143 -starttls imap -CApath /etc/ssl/certs CONNECTED(00000003) depth=2 C = IL, O = StartCom Ltd., OU = Secure Digital Certificate Signing, CN = StartCom Certification Authority verify return:1 depth=1 C = IL, O = StartCom Ltd., OU = Secure Digital Certificate Signing, CN = StartCom Class 1 Primary Intermediate Server CA verify return:1 depth=0 description = 7t3YlXVfb6bVQ2pp, C = US, CN = mail.gedalya.net, emailAddress = [email protected] verify return:1 --- Certificate chain 0 s:/description=7t3YlXVfb6bVQ2pp/C=US/CN=mail.gedalya.net/[email protected] i:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Class 1 Primary Intermediate Server CA 1 s:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Class 1 Primary Intermediate Server CA i:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority 2 s:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority i:/C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority ---
