Some of you have neat sayings beneath your signature. A good one in this thread is "Conjecture is just a conclusion based on incomplete information. It isn't a fact.".
I'm seeing comments implying that messages from yahoo-based member accounts are not reaching members with gmail-based member accounts. I'm wondering if this might be one of those conjectures based on incomplete information. Has anyone actually tried to diagnose the problem?
Unfortunately, it is not conjecture. :(
Are the messages disappearing because
- I use HYPERKITTY to post them?
- my account is based on a yahoo e-mail address?
- your account is based on a gmail e-mail address?
- something else?
(I realize there could be more than one cause.)
It's primarily because your address is @yahoo.com. In 2014, Yahoo began using an agressive DMARC setting with a policy to reject all yahoo.com mail that fails DMARC. Not all domains which recieve mail respect this, but Gmail is one that does. That's why list messages from @yahoo.com addresses don't reach users @gmail.com.
I am not familiar enough with DMARC and Mailman3 to know whether there are any work-arounds available for this issue or not. There aren't any great solutions to it, in any case. If someone knows differently it would be great if they could reach out to the Fedora Infrastructure team with details (ideally in the form of a patch ;) ).
