I know I can make an Outgoing content filter to apply a disclaimer text resource, and I know I can go into text resources to write a disclaimer, but we are looking for the ability to 'brand' all outgoing e-mails with our company logo and standard disclaimer at the bottom.
Currently we use a MailMethods appliance, which does this... but we may look at getting rid of the Mail Methods device, so we want a simpler in house way to do this. MailMethods also can apply advertisements to e-mail, but that has not been proved sucessful, so were scrapping that idea.
In Text Resources, I tried to make a disclaimer with HTML to point to an image hosted on our webserver, but it appears as it if converts this to text and does not actually display the rendered HTML.
I've tried variations, without the html tags, but it made no difference.
So is this something Ironport can do, or do we have to back up a step and see if Exchange 2007 can do this proccessing before it gets to the IronPort in the delivery path.
Email should be branded like:
Body of E-mail
Dislaimer ... The information contained herein is intended only for the recipient of this message. blah blah blah.
There is an action that says skip remaining content filters so you could use this to weed out those emails that already have the disclaimer and then have the next filter action add disclaimer text. I don't know why the test for RE: and FW: are not working, but be aware that other countries use different abbreviations for RE: and FW:
