I have set up the following incoming content filter to bounce messages with executable content:
executableFileBounce: if (attachment-filetype == "Executable") { bounce(); }
It works fine, however, it gives the sender the following bounce text which is not very descriptive:
5.x.0 - Message bounced by administrator
Can anyone shed some light as to how to change this message to something like "Message bounced because it has an executable (EXE) or other prohibited attachment"?
