Block webmail attachments

A task was set:

  • Block sending file in webmail of popular mail services: yandex/mail/google/rambler.

To do that you should edit Global Configuration by adding the following list of URLs to the “Rules-> Access -> Sites”


This will block the ability to send files to popular mail services. In a similar way, other file sharing services ca be blocked to prevent leak of corporate information.


I you don’t want to block sending attachments for all users at once you should add the corresponding exclusions on the configuration page in “Internet - > Rules: Access - Sites”
