The faster folder index check for IMAP folders was backported from phlyMail 4. This increases the indexing speed by a factor 30 or more. If GZip is active in the front end, all AJAX calls now get compressed too. This should generally increase the front end's speed. A fix was made in the SMTP class, which is now much more compliant to standards. TLS is supported in the SMTP layer. There is experimental support for AUTH CRAM-SHA1 and AUTH CRAM-SHA256 in the POP3 and SMTP layers. Handling of inline emails was improved.
