E-Mail an Versender mit geblockten Inhalten

Hallo Jörg,

Herzlich willkommen hier in der Community !

(Sorry, my German-speaking brain isn't creating thoughts at the moment. [:(])

I don't know of any way to do this.

MfG - Bob (Bitte auf Deutsch weiterhin.)

Thanks anyway Bob. I wonder if there is a solution possible because e-mails go first to firewall and after that to the mail server.

I think there's nothing to do in the UTM, Jörg, but maybe your mail server can look at the headers and alert the sender.  If you were using Intercept X or Sandstorm, you probably wouldn't need to block .doc files - check with your Sophos partner.

Cheers & mfG - Bob

This feature would be highly appreciated.

As we are trying to "educate" our partners NOT to send Office-Documents as attachments where possible, an automated response for these Mails

could do a lot of automated work in this case.

Kind Regards, 

Please post that suggestion at Ideas and then post the link back here in this thread.

Cheers - Bob

Any form of email response to a sender is discouraged by the experts, because it can cause backscatter.   If the spammer uses a fraudulent identity to hammer you, your responses can be used to hammer the person whose identity he has borrowed, and maybe get you blacklisted as a result.  To prevent this, the ideal is for the perimeter spam filter to reject the message, and let that be the only feedback.   

Notwithstanding what I just said, this is how UTM behaves:

If a failure is detected after the message is accepted, there is no possibility to notify using rejection.  In these cases, UTM will send a non-delivery report (NDR).   I would prefer to have control over this behavior, but there is not one.   I have see this on a mail server where recipient verification cannot be done using LDAP during message reception.
