Maybe they don't support IMAP w/ STARTTLS over port 143, but only IMAPS (port 993)?  I.e. you have to say

openssl s_client -connect your.provider.com:993

as to negotiate the ssl connection *before* starting the protocol.  At least for yahoo, this works:

albrecht@deneb:~$ openssl s_client -connect imap.mail.yahoo.com:993
[... snip the certificate stuff ...]

I.e. yahoo doesn't support CRAM-MD5, only LOGIN and PLAIN (plus some non-standard extensions like XOAUTH2, 
etc.).

Cheers,
Albrecht.
