I'm not saying I agree that an A/V company is right to put their tagline into the message, especially if it breaks DKIM. If I owned an A/V company, I wouldn't do it [1].
However, I understand why A/V companies would do it - it (presumably) helps drive revenue because it increases visibility in a way that putting it into a header does not. -- Terry [1] This is easy for me to say because I don't own an A/V company and my revenue stream does not depend on it. -----Original Message----- From: Dave Crocker [mailto:d...@dcrocker.net] Sent: Monday, September 15, 2014 5:27 PM To: Terry Zink; Murray S.
