I have searched the forum but no results for my problem.
An user did send some days ago an email with a .docx attachment.
The attachment was banned and I can find the following message in the admin mailbox:
No viruses were found.
Banned name: .wmf,docProps/thumbnail.wmf
Content type: Banned
Internal reference code for the message is 03749-08/AO8Y0kLKEmzc
First upstream SMTP client IP address: [xxx.xxx.xxx.xxx]
According to a 'Received:' trace, the message apparently originated at:
[xxx.xxx.xxx.xxx], mailserver.xxxxx.xxxx.it mailserver.xxxxx.xxxx.it
From: Xxxxxx Xxxxxxx <firstname.lastname@example.org>
Message-ID: <4780602.378.1297765870603.JavaMail.root@mailserve r>
The message has been quarantined as: banned-AO8Y0kLKEmzc
The message WAS NOT relayed to:
554 5.7.0 Reject, id=03749-08 - BANNED: .wmf,docProps/thumbnail.wmf
But the sender was not informed of the blocked email.
I have tried to send a banned extension file and zimbra does not allow sending the message but if I try to send that .docx file the message seems to be accepted for delivery.
It has been tested with zimbra webmail and with thunderbird, same results.
It is a problem because if a message is blocked the sender must be informed of this.
Any help is appreciated.
