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 = ______ at gedalya.net
verify return:1
