An IETF friend of mine is trying to set up a personal domain at hosting company Pair.
When he sends mail to a verizon.net recipient, which is hosted at AOLYahoo, it rejects it after data with 554 Message not allowed - [PH01] Email not accepted for policy reasons. Please visit https://postmaster.yahooinc.com/error-codes (in reply to end of DATA command) These are low volume personal messages. His domain housley.us was registered two years ago but I don't think has been used for mail before. I looked at Pair's outgoing mail to my system which looks quite clean, and he says other people can send from Pair to Yahoo, so my guess is that it doesn't like getting mail from new domains, even at low volume. Any suggestions? Pair's support has no ideas. R's, John _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
