-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I am trying to help a very small isp with a yahoo.com delivery issue. They are getting "421 4.7.0 [TS02] Messages from 208.88.52.225 temporarily deferred - 4.16.56.1; see http://postmaster.yahoo.com/errors/421-ts02.html"; errors.
Volume is less than 50 total messages per day going to yahoo.com addresses. Clients use their own domain names. https://help.yahoo.com/kb/account/yahoo-complaint-feedback-loop- service-faq-sln26007.html says "For bulk commercial senders or senders of transactional mail, DomainKeys or DKIM is the best option. ISPs should contact Yahoo for other options.", but gives no contact address for an ISP. Is that a mistake? Is the Yahoo feedback loop only available for folks that DKIM sign outbound mail? -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEAREKAAYFAlb5qy0ACgkQL6j7milTFsHaOQCbBS7FforwdSURhEDfSn9p6ujK n+wAoIFRSmuzrqFH+pmcHDS5luzS5koJ =79zs -----END PGP SIGNATURE----- _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
