Yahoo DMARC stupidity
28 April 2014
Following recent changes at Yahoo [and now AOL] with regards to their DMARC email policy settings, emails sent from your website on behalf of users with Yahoo email address will no longer arrive in your Inbox with the correct "From:" address.
Instead they will appear to come from "do_not_reply" at one of our local addresses. The "Reply-To:" address will still show the user's Yahoo address, but this is not universally recognised by all mail clients. Please verify the target address when replying.
Also, if you are subscribed to any third-party mailing lists and using a yahoo.com email address when posting to them, emails you send to those lists may now bounce. The only real solution is to use a different email address.
