I got it set right now to quartine any message with a blank subject from an AOL account and then BCC me so I know something tripped the filter.
I have a military email account and they strip all links in a message and replace it with a redirect to a banner page saying it was stripped by policy. I did not know if Ironport could also do something like that.
There is a Message filter action called "Edit-body-text" which can replace text in the body of the email with other text, e.g. a message and a link to a web page somewhere which can show you the banner page you create?
If you look at ESA 7.5 Advanced guide.pdf on page 6-90-91 Edit Body Text Action it can show how to replace a URL and if you combine this with an if statement matching no subject and maybe AOL it can do what you want?
I just learnt about message filters so be careful with them, especially the Edit-body-text action since they are applied on all in/out emails it can have unintended side effects.
