Re: [EXTERNAL] Re: [SECURITY] Email Banner

It does interfere with the signatures, so we’ve taken the approach to only add it only “common phishing sources” which 
includes public email sources and only on email that will be delivered internally (post-signature validation and not 
forwarded to another address).

It does for us.  With the change in the subject and the banner inclusion, the signed emails end up being an attachment. 
 It’s not a huge headache, but it’s an extra click to open.

I am looking for information on who has implemented an external email banner and who has not.  For those that have, 
have you seen an improvement in user behavior around phishing?  Thank you for your time.

Does adding these banners interfere with digital signatures on messages?
