>From your first paragraph there, are you referring to the "Allow
Multiple HTML Signatures" setting? I tried that setting using an image
tag without a src and it doesn't work for me because some email client
change the <img> tag that is missing the src to an error message and
thus MailScanner won't see it when it comes back in.
