blacklisted

I am receiving the following message on my iPhone mail account - "Temporarily blacklisted IP Address - try again later."  My comcast.net email address is working fine on my Windows-based computer using Outlook.  How do I get this resolved on my iPhone?

Hi user_gjw3a! Thanks for taking the time to visit our Xfinity Forum regarding this email concern. We appreciate you being a customer, and my team is here to support you. The error "Temporarily blacklisted IP Address - try again later" may occur if your IP address has been flagged due to high outbound email traffic or spam activity. Additionally, you would want to ensure your device is secure and free from viruses, as they can contribute to such issues. 

 

I'm glad to hear you can access your Xfinity email through Outlook on your computer, but I understand you can't access your Xfinity email through Outlook on your iPhone. For troubleshooting purposes, are you able to successfully access your email through the Xfinity web portal directly [connect.xfinity.com] on your iPhone? 

 

Also, please note that sending unsolicited direct messages is a violation of our forum guidelines. You must first create a Public post requesting assistance, and once a Comcast-verified employee responds and asks for a direct message to be sent, you can then proceed with doing so. This is just a heads-up for future reference, but we look forward to further assisting you.

Thanks for your response.  Just to be clear, I am using the Mail app on my iPhone, not Outlook.  I am able to view my email using the Xfinity app on my phone.

Have you gotten a chance to review your iPhone settings to ensure they are up-to-date with IMAP? Check out our article here to get instructions on how to verify those settings and get them updated if needed.

Not sure if y'all did something or the problem resolved itself on its own, but my email returned (all unread) about 3 hours after my initial post.  Thanks!
