September 3, 2020

MetaDefender Email Gateway Security 5.0.3 is a maintenance release focusing on performance improvements and minor fixes.

Fixed


Increasing delay in email delilvery

Due to sub-optimal database queries introduced in Release Notes/Version 5.0.2, under certain circumstances Email Gateway Security may have caused increasing delay in email delivery.

Email scan failure due to timeout

Under certain circumstances Proactive Phishing Prevention's URL rewriting functionality threw an error causing emails to fail to scan.

Consecutive rescan notifications

When password protected attachments contained blocked contents, rescan erroneously succeeded and resulted in consecutive rescan notifications due to the presence of the blocked content inside the encrypted archive file. For details about handling password protected attachments see Operating/Password protected attachments.

Rescan gave misleading message

Under certain circumstances rescan gave a misleading message implicating that the rescan failed. For details about rescanning emails see Operating/Quarantine.
