Yes, I'm pretty sure it's problem with RC - it uses TLSv1.2 for IMAP connections but not for SMTP. PHP is rather new (Debian 7):

I'm afraid you need PHP 5.6 according to this http://php.net/manual/en/function.stream-socket-enable-crypto.php

I have no idea how did you get IMAP connection to use TLS 1.2. As I've said both SMTP and IMAP code use the same way of setting TLS.

ps. PHP 5.4 is no longer supported by PHP.
