we are trying to block users from being able to add and send attachments in web mail accounts (such as gmail, hotmail etc). We have tried using the Media Type filtering rules, but we can still upload files in webmail. Is anyone aware of any other method of blocking a user from uploading files via webmail?
Sorry, should have mentioned all of this! IT is MWG 7.1.0. Webmail tested was gmail ahd hotmail. We attempted to upload the following file types: PDF, .ZIP, .JPG, .DOCX and .PNG. All of these file types were permitted to be uploaded. In the rule set we have selected all media types to trigger the rule.
Another question - does SSL Scanner is enabled? Gmail & Hotmail use https, so without SSL Scanner we won't able to scan attachments.
I just checked with my development version (7.2) and it blocked MS Word file without any problem. If SSL Scanner is enabled, and MWG still don't block attachments, then please file a bug via support
