I guess it's possible that some users simply marked mailing list mails as spam and we got blacklisted because of that. The reject message is this: 421 4.7.1 [TS03] All messages from 5.9.250.164 will be permanently deferred; Retrying will NOT succeed.

I've finally gotten around to setting up and testing DMARC for my domain and I've set up mailman to munge From for DMARC messages. Sadly, I still haven't heard back from yahoo, but I guess their postmaster@ address really just goes to /dev/null. Too bad. I don't know when yahoo will start accepting mail again though and from a quick look at the log it seems that they always reject the mail directly at MAIL FROM time or don't even accept the connection/let it time out. That also means they will probably not notice that we've changed the configuration for DMARC mails. Thanks for your input I guess, but this will probably not be resolved any time soon.
