6.2.1 Version 4.4.1

4.4.1 MetaDefender Email Security release

19 September, 2018

MetaDefender Email Security 4.4.1 is a maintenance release focused on fixing missing rescan links when infected attachments are present.


Rescan link was missing from encrypted archive disclaimers

When disclaimers for encrypted archives was enabled with the action "Delete Blocked Contents", the rescan link was missing from the disclaimer even if the public server address was filled out and if there was an infected attachment next to the encrypted archive.

Zero byte emails resulted in warnings and failed emails

When MetaDefender Email Security received an email which had absolutely no content (0 bytes: no headers, no body, no attachments), the processing of this email resulted in warnings and the email went into a failed state. These emails are now rejected as they only contain sender and recipient info, but nothing else.
