I believe that the issues are specific to individual wards only in the sense that individuals are organized in wards and so each ward will have it's own unique set of individuals who are unable to receive said emails. I don't believe that ISPs are blocking things because of a "ward". There is no way for an ISP to identify a "ward" or even individuals in a "ward" using just their email address. In fact, the ISP never actually sees the email address of the person who sends the email, at least not during any SMTP transaction. The SMTP envelope from generally has the form of:russellhltn wrote: ↑Fri Oct 04, 2024 7:05 pm Just from watching the messages, it seems like the issues are ward specific. I'm suspecting that someone on the domain flagged the emails as spam and now all the email from that ward (or perhaps from that individual sender) are flagged as spam for everyone on that email domain.

And the From header generally looks like:
Firstname Lastname <noreply-lcr@mail.churchofjesuschrist.org>
The actual email address of the member who is using LCR to send a message is included in a Reply-to header.
So the things that could potentially be blocked by an ISP are:
1) the SMTP envelope from address, or
2) if they do in-depth content scanning they may block the email based upon the fact that <noreply-lcr@mail.churchofjesuschrist.org> exists in the message headers. If they did that, however, that would block it for everyone (which doesn't seem to fit the "ward specific" hypothesis). Similarly, the ISP could block based upon the presence of @amazonses.com in the envelope from. But this too would have the effect of blocking it for everyone.
3) An ISP could also potentially scan a message for the Reply-to header and block based upon those contents, but that would then just mean that this one particular sender would be unable to use LCR to send things.
4) There is another option as to what could be blocked... the sending server's IP or network. For example, in a recent communication sent out via LCR I see IP address 54.240.9.156 which is a9-156.smtp-out.amazonses.com. If an ISP decided to block Amazon networks from delivering emails, that would impact more than just the Church, it would also impact other companies who use Amazon for delivering emails.
It seems that the Church LCR system no longer sends out emails directly using it's own IPs as it once did. Perhaps because they think Amazon will have a more reliable mechanism for delivering emails.
There may be a combination of all four happening in the wild, however, I don't think many of these are what is causing the majority of the problems.
As I've said elsewhere, I believe that there is a blacklist of some kind that is the source of the problem, and certain members of different wards somehow end up on this list. Whether the Church maintains this list and filters out those recipients when submitting to Amazon, or whether it is Amazon who is maintaining the blacklist, the effect is the same. Those members who are on it are unable to receive emails from LCR, even though their email addresses work fine everywhere else. I susepct the blacklist is internal to the Church because this problem has existed long before they started delegating delivery of emails to Amazon. So it makes it look like problems are "ward specific" but that's only because there is a random distribution of the blocking throughout the wards in the Church.
