Mail server improvements

Rename users
Duplicate detection based on "Message-ID" disabled. Reason is an incorrect multiple usage by Outlook
Users can no longer revoke administration rights (IMAP ACLs) for their own folders
E-mails with invalid sender addresses are rejected at the SMTP level instead of being accepted and bounced as before
Newly installed systems with this version allow emails with EMF and WMF attachments to pass by default, as they no longer pose a threat to systems running Windows XP SP2 and later. In case of an update, the behavior remains unchanged
