 Installations with uw-imap server should set imap_disabled_caps = array('ESEARCH')
 in main configuration file. ESEARCH implementation in this server is broken (#1489184).
+
+PHP >= 5.6 validates the ssl certificates by default. It means that
+if IMAP/SMTP certificates are self-signed or use wrong host name you'll get
+connection errors. A solution in such cases is to set imap_conn_options,
+smtp_conn_options and managesieve_conn_options in a way described in config/defaults.inc.php.
