    Obviously, your mail server has to point to the UTM for outgoing mail rather than directly going to the internet. If it's not set, point your mail server to the UTM and under the relaying tab, add you mail server to the allowed host relays so the UTM will accept email from it.

    Then you would set scan outgoing mail in the smtp proxy under the relaying tab.

    Then under malware, there are blocked file extensions to which you add the extension there.

    The above is for mail coming in and I would think that by setting scan outgoing mail, the same rules would apply.

    i got the Issues solved. 

    I did a Exception under Email Protection -- SMTP -- Exception

     

    Skipping -- Expression blocking: I pointed the Subnet wrong.

     

    After the correction, no file with XLSM was sent outside
