Block users from sending attachments on their external webmail

[tvliew]

Hi All,

I am have been searching and trying out if it is possible if Untangle can blocking internal users from sending attachments on their Yahoo! Mail, GMail or Hotmail. Is this possible on the INTRUSION PREVENTION plugin or do I need the WEB FILTER to do this?

It's technically impossible to do this as the connection is encrypted.
