Hi, is there any document where we could see in which type of files can Email Security appliance look for a string?. I would like to create an Outgoing content filter that looks "inside" the attach for a string. I think that you can do this in PDF and office documents but I'm not completely sure and also I don't know in which other file types you can look for.
The final step should be look for a string,"Confidential" for instance, and if the mail is not encrypted drop it. If there is "confidential", string the email must be encrypted, and this word could be inside Word document.
¿Is it possible?
Thank you in advance
Samuel
