I know that there is already a thread regarding password encrypted ZIP files...

This is a little different request...
First: I do not necessarily want to turn off the feature in Zimbra that blocks password encrypted ZIP files...
Second: The file being sent must be encrypted...

As part of a process, a password protected ZIP file is being generated and is sent to the receipent...

The password is ALWAYS the same in every password protected ZIP file.

Is there a way that the KNOWN password can be used within Zimbra so the anti-virus process can still check the ZIP file?

Or is there a way that a specific user can be granted the right to send password protected ZIP files?
