Reject mail with specific file extensions

Globba
Hi!

I need to reject mail that contains files with special extensions (for example, .exe).
When I put .exe into email protection -> smtp -> antivirus -> file extention filter, UTM begins to quarantine mails with .exe files.
But how can I   reject such mails?

Thanks!

    Eventhough it's 5 years old: Is there no option? We have a bunch of people still trying to send .xls/doc documents instead of the XML pendants, which are a security risk. Currently the UTMs just quarantine them - I'd like to reject them!

    The sender doesn't know he's sending 13 years depricated stuff and expects it to be delivered.

    Any solutions for that?

    No, but actually we have exactly the same problem. It's a shame that Sophos does not offer a solution to this. Especially as this would be a considerable gain in security. So +1 ( even if this is not the platform for ideas)

    Best regards

    Don't +1 here, there's a fuction on the top-right side of this page... maybe if a billion people ring that bell, Sophos will do something (overdue) for their money. ;-)

    Thanks for pointing that out, I was the second one that already did that. Unfortunately Sophos seems to push more development power into XG since years and still XG can’t replace UTM. But that’s another story.
    I think one will need a separate mail gateway to use such functions in the near future too.

    Guys, there might be a way to do this with exim, but you won't find it here.  Maybe on exim.org or github.

    You know if The XG things can do this? Someone else I know - who's obviously not using Sophos - has a 'replacement' function, that gives the receiver a textfile telling what's missing and that it got blocked and could be released by admin.
    That's at least better than just dropping the mail into quarantine.
