It's a nightmare, as the DMARC record on Yahoo email addresses can cause any other member's email address to bounce (and be removed). The DMARC record tells receivers to reject the email if not received directly from Yahoo. So [email protected] sends an email to the list, the list forwards to [email protected], [email protected] rejects as it's not directly from yahoo.com. [email protected] then clocks up a bounce failure within the list software. The only solution is for the list software to be altered to rewrite the from address of DMARC domains, or for people with DMARC domains (e.g. @yahoo.co.uk) to use a different email address to send to the list (e.g. Gmail) As someone has already said, DMARC was never envisaged for this sort of use (instead it's for @paypal.com etc), but it looks like it's here to stay (or at least until if/when ARC is implemented for email forwarding).
