Block specific extensions

Hey PepijnDeneut 

Have you tried blocking this file type extension via web policy (with HTTPS decrypt and scan)?

Hi Flo,

I meant in mail policies. Not web policies?

Hey Pepijn,

My apologies for the confusion. Please create a File Type category defining this .iqy file extension, then create an SMTP policy that is configured to block this File Type category via the File Protection section.

Regards,

SMTP is only for outgoingmail, but I want block inbound mails attachment with xls .

Yes, i got the same problem. In UTM you can create POP3 rules with exactly this function. [^o)]

Hey Alexander Fox 

This would work for inbound mail as well.

Thats my settting SMTP Rulez. When I send mail from outside to the Domain the excel File works.

Would it be possible to enable the support access tunnel for your appliance and PM me with the ID?

I'd like to investigate the file type definitions that you configured for this.

Thanks,

In your provided screenshot for your SMTP File Protection policy, you have highlighted all of the MIME Types to be part of the MIME White List. Please de-select the excel related MIME Types in order to block them properly.

I have change and marked only the Office Apps under Block File Types
and Word and Excel come to the user. No effect.
