ForeFront and Digitally Signed Emails RRS feed

  • Question

  • Hi everyone,

    I'm having an issue with Digitally signed emails and (assuming) Forefront for Exchange. When users send or recieve Digitally signed emails to people they come through fine. However, when they send an email with any attachement, the email comes through with a cert error stating it is not valid, and has been possibly tampered with (or something to that effect).

    Any idea what would cause this behavior?
