So the issue is that i have been trying to send a mail from my server with xlsx file extension attachment but zimbra rejects the mail giving a message content is band
BANNED CONTENTS ALERT
Our content checker found
banned name: .asc,docProps/app.xml
in an email to you from:
And same time another mail arrives in the inbox which looks like this:
No viruses were found.
Banned name: .asc,docProps/app.xml
Content type: Banned
Internal reference code for the message is 21005-02/Sppi_Gv8AtCP
First upstream SMTP client IP address:
I have checked in the admin console > configuration> global settings > attachments > currently blocked extension
But xlsx is not listed there
So are there any solutions
