I have postfix setup to relay through Sonic and this generally works fine, but tonight I started to get
"Diagnostic-Code: SMTP; 554 Message not allowed - [PH01] Email not accepted for policy reasons. Please visit https://postmaster.yahooinc.com/error-code"
bounces from anything sent to an @yahoo.com address. Sending email to yahoo through webmail on sonic works. N.b. the link is completely useless, rewrites to a yahoo mail landing page.
Any thoughts on what's up? I'm guessing something DNS or SPF-related but without full headers from yahoo, can't diagnose much. Sending mail to a gmail address works fine and shows SPF passing on IP 64.142.111.50 (which is not the Sonic relayhost IP, but is in a Sonic block).
