What version of SSL are you using? There was a problem with the update
of "openssl-1.0.1a" that caused problems with Postfix with certain
domains.

Try this for starters:

openssl s_client -connect 127.0.0.1:443 -tls1_2
openssl s_client -connect 127.0.0.1:443 -tls1_1
openssl s_client -connect 127.0.0.1:443 -tls1
openssl s_client -connect 127.0.0.1:443 -ssl3

Post the connect or fail results back here.
