Sorry, one other thing I wanted to add. You have no control over mail DELIVERY to any domain that is not under your control. Even if everything in the headers is perfectly correct and the recipient exists at the domain and the messages is sent to the right server and accepted, whether the message is DELIVERED is entirely out of your control. As one famous example, at one point Verizon device that they could reduce their spam load by discarding all emails that originated outside the US. They did not reject the emails, they did not notify other the sender nor the recipient that the messages were not delivered, they simply discarded them. There was absolutely nothing that any mail admin could do about this. Similarly, my wife’s employer used to very often discard messages sent with attachments, including at times internal mail from department heads to employees. One year, no one got their W2’s (their ’solution’ was to send a link to the W2 pdf in the form http://compaydomain/SSN/2011-W2.pdf). Again, no bounce, reject, or notice to either sender or recipient. Which messages? Who knows? Do they still do this? No idea, my wife stopped having anyone send mail to her work account and now only gets internal mail (and lots and lots of spam, of course, since their IT department, as should be obvious from this story, is entirely incompetent at handling mail). Something about this should be in your aforementioned FAQ as well. Just because the Postal service delivers a letter to an address doesn’t mean the people there do not put the mail directly into the shredder. -- Si Hoc Legere Scis Nimium Eruditionis Habes
