I have the following question, is it possible to block a email based on a file inside a compressed file (zip, rar) attached to the email? how?
for example the email has attached the file "compressedfile.zip" and inside this zip there is a file called "virus#"$"#$#".exe" can i block based on the uncompressed file for example with a regular expression (virus*.exe)? or other method.
Re: Email Gateway Block based in uncompressed file
The one catch to this answer is that if you have a rule which explicitly allows ZIPs through, you need to check the box for that rule which tells the MEG to continue scanning. If you do not, the MEG will encounter the zip, decide that it's allowed, and then not scan any further to see if there's anything that's not allowed.
