I got several replies but no solutions, other than having them migrated to other systems, which is not possible. In the General options, I set DMARC to both NO and MUNGE with the same results. I have more than 200 subscribers and only the Yahoo and AOL users are having this issue, so there must be a setting that we can change to make it work with them also. I am surprised that it hasn't popped up yet with you guys, or maybe your users haven't reported these issues since they are not getting the emails in the 1st place!

Note that I realized the issue when they noticed some replies to emails that they haven't seen...
All of them without exception are not getting back their own posts.

Hope a suggestion would finally make it work.

PS: when I reply to this list, it goes only to the poster, shouldn't it go to the list? I don't have the habit of doing reply all.

I am having issues with group emails sent to AOL, Yahoo email and
similar systems.
They are either not receiving their own posts or not receiving random
ones even in their junk folder and by logging to the web version.

See the email below as an example and I also logged in to his system,
did search and troubleshooting without finding those lost emails.
Have you encountered similar issues? any suggestions?

Note the below Rogers account is actually a Yahoo based email.

Likely a DMARC issue. You need to enable the DMARC mitigations. AOL,
Yahoo and the like will not accept messages with a From that says AOL or
YAHOO that passes through your list unless it doesn't modify the message
body or subject in any way.
Even with proper DMARC mitigations, Yahoo will likely defer messages and/or
deliver messages from Mailman lists to peoples' spam folders.
