I configured web post protection rule to block all files and then just mail yahoo and hotmail work fine when block files attachment but gmail is Not. Any body here see this problems? Thanks for advance!
Yes, Hotmail and Yahoo using http but Gmail using https. Maybe that's problem DLP can not apply policy. Hope McAfee take a look this problem for future version
I am not sure if anybody can...!!
You need to break the encrypted secure traffic if you want to do that .. the same reason why no anti-virus can scan and clean an encrypted file....
