I am seeing the similar behavior with Horde 5.2.1 & IMP 6.2.1 after 
updating from PHP 5.6 RC3 to PHP 5.6 RC4 (Debian) today.  After the 
update I see these log entries for Horde and Cyrus IMAP and Imp reports 
a problem communicating with the server.

If I turn TLS off with $servers ['advanced']['secure'] = false; 
everything works fine.

I confirmed that the only changes to our php.ini was to reset the 
max_upload_filesze to 2MB and it set expose_php = off.

I opened ticket # 1349 for this.
