We have 4 email gateway's, 2 per data centre and clustered. The idea was to use them just to scan incoming and outgoing email generated by our application, we were advised that this is possible so we bought them.
What we would like, for outgoing email, is to have the email sent to them from a mail server, have it scanned and then sent back to the originating mail server for sending it on. The only options I have come across are to either use the domains area and utilise it as if all email were incoming (which won't work as I do not know every active domain in the world + there are limits there) or use relay which doesn't do what we need. Is anyone aware of a way to just use the gateway as a simple scanner for outgoing email?
Thanks in advance.
