Seeing an error code in Yahoo Mail can be confusing and frustrating if you're unsure what it means. Here's a list of the common errors that can have been seen when trying to access or send email.
- Error 2/14/15: These errors essentially mean the same thing: there's an error on our end that's causing the mailbox not to display. They don't mean the mailbox has been erased (unless it's been over a year since you accessed it). If you haven't accessed your email in a long time and are seeing Error 14, it's most likely related to a known issue. If you've been accessing your account and see Error 14, then most likely there is a temporary issue on our end that needs fixing.
- This user doesn't have a yahoo.com account: This error is most commonly seen when the recipient's address being input incorrectly. Keep in mind that if an address has a locale-specific domain (like .co.uk, .ca, etc.), then the email needs to sent to that address. If not, then it will bounce with this error. Keep in mind that all new Yahoo addresses are created as yahoo.com that locale-specific addresses are no longer available.
-TSS04/06/09: These are typically seen when a bulk mailer like a company or business is sending to Yahoo. It's usually related to the amount of Spam coming from your IP address and needs to be addressed by our Postmaster team.
- 554 5.7.9 Message not accepted for policy reasons: This is a DMARC-related error. Either your domain isn't using DMARC records when sending to Yahoo, or Yahoo wasn't able to determine the email is coming from who it says it is. This can be due to incorrect settings in Mail apps, breaking the authentication process through redirects, etc. Review this help article for more information on our DMARC policy.
