Block Downloads for WebMail

Hi,

I think I have a pretty straightforward problem but I can't find a workable solution:

I'd like to block all downloads from Webmailers without blocking the site completely or blocking downloads from other sites.

Does anybody have a good solution?

Suggestions are highly appreciated!

Cheers
Chris

Hi Chris,

If the 'File Extensions Filter' on the 'Malware' tab doesn't offer what you need, please give us an example of an email you want to allow to be read that contains a download you want to block.

Cheers - Bob

hi

just edit your filter action and in the download section you can block all extensions you want.

Good lock

A private e-mail from a friend with an attached office document, that has a funny picture in it and a malicious script- sent to a Googlemail account.

The user should be able to read the mail, but not download the attachment.

But I want to block the downloads only for a certain category or at least for only a bunch of sites.

This should work, but it may be awkward in the future when you have other rules that you want to apply.

In the Filter Action, block specific file types for all sites.

Then, create an Exception object to bypass Extension Blocking and MIME Type Blocking for any allowed categories OTHER THAN Personal Webmail.
