    The IP WAS blocked by spamhaus a few days ago, but that has since been corrected. And in this case, Yahoo has not updated their records. Based on Yahoo's configuration, they advise to allow up to 48 hours for this to clear up on their side. We understand how important your ability to send emails to your recipients is and we are looking for ways to get this cleared up sooner with Yahoo.

  • Thanks for your feedback, its good to know this has already been resolved with Spamhaus and Yahoo are typically slow to respond to technical issues. I'll kerp checking over the next few days to see if Yahoo resolve this.
