Also try reading through the error message slowly and listen to what it's saying.
Most bounce messages will give you a reason as to why the message didn't go through. -----Original Message----- From: macvisionaries@googlegroups.com <macvisionaries@googlegroups.com> On Behalf Of Jonathan Cohn Sent: Friday, 11 January 2019 7:46 AM To: macvisionaries@googlegroups.com Subject: Re: Mysterious "failure" messages on Mail Hello, Do you request return receipts or automatically attach a picture or link in your e-mail messages? Without specific text of the rejection it is hard to guess what filters are being triggered and where. It might even be possible to declare yourself as a safe sender and get around some of the issues. But I suspect that iCloud is not trusting something in your message. I expect it to be iCloud, because it seems that Google often is very quie about sending rejections. I suspect that this might be a way to honey pot spam messages. If you feel comfortable forwarding the exact error e-mail I will see if it sheds any more light on the issue. -- The following information is important for all members of the Mac Visionaries list.
