Mail Protection: Non-delivery report for blocked Outgoing messages
In my opinion its useful to receive a Non Delivery report for outgoing sended emails. Blocked file extensions like .exe or .bat will block ANY directions of mails (extern to intern and also intern to extern).
These messages will be quarantined however internal users will not receive any information about that like an NDR. He belief, that the mail was delivered correctly.
The internal user should get a NDR (Non Delivery Report) if his outgoing mail was blocked by mail filtering. e.g. via Quarantine Report.
Internal users get no NDR message if his outgoing mails was blocked by mail filtering.
The only way for users, to check out his user portal frequently, but this is not comfortable for users.
Only the admin can see this mails in SMTP Quarantine and release manually.

Was implemented in UTM 9. Extract from 9.0 release notes:
For SMTP Mail scanning, if you choose to scan outgoing messages, the sender will now get a
notification if one of their outgoing messages has been blocked by the system (e.g. for a virus

It's not only a good idea but a must. Not the admin but the user who sent it should receive na NDR. The Mail should also be delivered without the attachment.

I second that.
Also true for blocked messages quarantined as spam. When the option "Scan relayed (outgoing) messages" is enabled, the user ist not notified about this.
