You can sign into this URL:
https://lists.centos.org/mailman/listinfo/centos
... and change the settings. One of the settings is whether to "Receive your own posts to the list". Make sure it is marked as "yes".
it's been there always. Some mailing lists I do have this problem with, others work fine, and it's not the settings reason, certainly not that one setting and rest looks ok too. I wonder if Centos mailman uses some blocking/blacklisting? But then why the group gets my emails but me?
I believe that the issue is that yahoo updated their dmarc record a bit ago, so now won't accept mail, from 3rd-parties, that has an @yahoo... "mailfrom", as yours do on this list.
If the non-@yahoo mailing sender doesn't do what's necessary to deal with enforced dmarc, and your mail provider enforces dmarc, you won't see messages from @yahoo correspondents -- which is likely why you aren't seeing your own list messages. Additionally if a mailing list has enough @yahoo posters, this can generate sufficient bounces to get you kicked off the mailing list on a regular basis.
There are various ways for mailers/mailing lists to deal with the enforced dmarc. My understanding is that with Mailman, which this list uses, one has to upgrade to -3.
Email service providers can't send to/from Yahoo Mail addresses
Questions about our DMARC policy Why are my emails bouncing?
We've updated the DMARC record with "p=reject" for multiple Yahoo domains.
This means all DMARC compliant mail receivers (including Yahoo, Hotmail, and Gmail) are now bouncing emails sent as "@yahoo.com" addresses that aren't sent through Yahoo servers. Any messages without a proper Domain Keys Identified Mail (DKIM) signature or Sender Policy Framework (SPF) alignment will be rejected.
