I would appreciate suggestions on how to allow password-protected files with an extension of .ZIP (uppercase).
The Authentium antivirus quarantines these messages, despite extension bypass rules for "zip" and "ZIP".
The issue was reported back in 2011 in a support request but has never been resolved.
Can I used End User Quarantine Release and safely include these messages for release? Since they are related to Antivirus, I do not want to allow the recipient to release virus-containing messages!
