Hey folks, I opened a ticket with Yahoo, they have been deferring our mail from wikimedia.org with the following message:
421 4.7.0 [TSS04] Messages from 208.80.154.5 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; see https://postmaster.yahooinc.com/error-codes (in reply to MAIL FROM command)) I'm not sure why we started to trip their spam thresholds, I am not aware of any significant changes on the types of email we emit from Wikipedia and our related projects. Would love it if someone from Yahoo could reach out to me. Yours kindly, Jesse Hathaway, Wikimedia postmaster. _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
