blacklisted IP

Hello, I see others have had this problem. All of my @comcast.com e-mail accounts are now receiving the error message "Temporarily blacklisted IP address - Try again later". I'm using Apple's Mail. This is happening across all of my devices. I've opened a case, but have not heard back. What should I do to resolve this problem? I tried getting an update today by calling Xfinity, but the call was lost after holding for 55 minutes. Any help would be appreciated.

I did notice that one post dealt with being out of the US. I too am out of the US.

Thank you, RRM

@user_j3iafm Welcome to the Xfinity Forum, and thank you for posting your question here. We recommend configuring your Comcast email for IMAP and not POP (see additional information below).

POP vs. IMAP: POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are two different ways to get email in your email program. We recommend using IMAP for your Comcast.net email. POP can cause problems when checking your mail from more than one phone or computer because POP removes the mail from our server and delivers it to your device. IMAP makes it easier to sync your email on multiple devices because your folders and mail remain on our server until you move or delete them with your device. With IMAP, the email changes you make on one device, like your smartphone, are reflected on your other devices, like your laptop.

For additional information on how to correctly configure your comcast.net email address to either IMAP or POP, please see here: https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email

If you truly need assistance with blacklisted email addresses, you will need to fill out the request form found here: https://spa.xfinity.com/rbl

Please let us know if you have any other questions or need additional assistance.

Thank you for the quick response. I could not find anything inconsistent between my Account settings and your provided documentation. All three of the @comast.net e-mail accounts are receiving the same error. They have been working for years. Unfortunately this response didn't resolve my issue. Thank you, RRM

@XfinityJeniece One other thing. When I click on the link, https://spa.xfinity.com/rbl, I received the following error message;

Bad Request

Your browser sent a request that this server could not understand.

Thank you! RRM

@user_j3iafm thanks for reaching back out and confirming. I am showing that the link is working on my end. Have you checked the settings to confirm you are using IMAP?

When I copy the link into a browser, it works. I've opened a Report. Thank you.

I also am discussing this issue via X. But so far I have not received a solution to the problem.

@XfinityJeniece Yes, I can confirm that my account is using IMAP. The account was created at least a decade ago. I have not mad any changes to it. Thank you!

@user_j3iafm I sent you a private DM a moment ago. When you have a moment, can you look at it and reply?

@XfinityAngie Thank you. I'm new to this platform, and technology. I followed your directions and sent something to @Xfinity Support and also @XfinityDaveL, as he said he had DM'd me earlier. I could not see that DM. Thanks again.
