For the last couple months I have been getting bounces from yahoo and aol subscribers. Hundreds a day, depending on list traffic. I think some mail gets through to them (the yahoo subscribers) but a lot gets bounced, if not all. None of the the subscribers have complained anyway about not receiving messages.
Not sure what to do. I had been on Yahoo's what-cha-call-it when a user complains or marks a message as spam, I would be able to tell what users from a report Yahoo would send me. Assume I'm still subscribed to that service, but have not received any for a long time.. maybe this past summer got one or two. The bounces are similar to what follows:
" <user>@yahoo.com host mta5.am0.yahoodns.net [98.136.102.54] SMTP error from remote mail server after pipelined MAIL FROM:< nome-announce-bounces@nomekennelclub.com> SIZE=7608: 421 4.7.0 [TSS04] Messages from 198.252.110.38 temporarily deferred due to user complaints - 4.16.55.1; see https://help.yahoo.com/kb/postmaster/SLN3434.html: retry timeout exceeded"
I'm also getting a few bounces from .me and .icloud accounts.. But that may be a different issue.. I don't know:
" <user>@me.com host mx3.mail.icloud.com [17.178.97.72] SMTP error from remote mail server after end of data: 550 5.7.1 [CS01] Message rejected due to local policy. Please visit https://support.apple.com/en-us/HT204137"

Apple has recently started publishing p=quarantine for its {mac|me|icloud}.com domains. If you don't include p=quarantine (dmarc_quarantine_moderation_action = Yes) in your DMARC mitigations, you need to do so.

You are publishing a DMARC record for your domain. This may or may not be desirable depending on your situation, bet if you do this, you also need to ensure that all outgoing mail from your domain is DKIM signed.
What I was referring to is the DMARC mitigations within Mailman. I.e., in the web admin UI for your list at Privacy options... -> Sender filters, you want to ensure that dmarc_moderation_action is Munge From or Wrap Message as desired and dmarc_quarantine_moderation_action is Yes.
