This problem is affecting most of my mailing lists, and it appears to be due to a deliberate change by Yahoo:
https://wordtothewise.com/2014/04/brief-dmarc-primer/ https://wordtothewise.com/2014/04/example-bounces-due-yahoo-preject/ "Endusers can do a couple things . For one-to-one mail make sure you're using the Yahoo outgoing mail servers and that should fix the problem without you having to really make any change. For email to mailing lists you'll need to switch to an email address at another domain for that mailing list." As I understand it: Yahoo is telling recipient email services not to accept mail from Yahoo email addresses that doesn't come from Yahoo's servers. Since email on this mailing list, or other mailing lists, comes from non-Yahoo servers, Gmail and other recipients reject the mail, or mark it as spam, in accordance with Yahoo's request. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
