Dear Yahoo,
Rolia is a reputable social networking website founded in 2000. We've been using the email address of rolia@rolia.com to communicate with our registered members for many years.
However, recently we found that our members using yahoo emails could not receive our email communication. By checking the mail log, we found that basically all emails sent to yahoo servers got a state of "Deferred: 421 4.7.0 [TSS04]".
We have no problem with all other email service providers, such as gmail, hotmail, protonmail, etc. So we believe that the issue is very likely caused by the settings on the yahoo servers.
If you can kindly take a look in your system and make changes accordingly to unblock rolia.com, it would be highly appreciated.
Best Regards,
