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”
api/v1/messages/attaches/add mail.rambler.ru/upload web-api/upload-attachment mail.google.com/_/upload
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”
