Added a limit so that hMailServer never processes more than five DKIM-Signature headers in a single email message (to prevent different types of abuse).
Administrator: The numbers on the Status page is now refreshed automatically.
Installation: If the user is using an old version of the internal MySQL database and tries to upgrade to v5 before first installing the latest v4-build, the hMailServer installation program will stop.
Installation: If a user is using v4 with the internal database, uninstalls hMailServer (and MySQL) and then upgrades to version 5, the hMailServer installation program will stop. A user cannot do this, since he will then not have any MySQL installation.
POP3: When a user logs on, any message which has been marked by deletion by his IMAP client but not been deleted will have it's \Deleted flag removed. This is to prevent issues for users who are using both POP3 and IMAP to access the same mailbox.
Other: OpenSSL has been upgraded to 0.9.8k.
Other: Data Directory Synchronizer has been added to the hMailServer group in the Start menu.
