11/27/17. For a few weeks now, various people are reporting that they are receiving roadrunner server rejections (message not delivered) when emailing me at …. nc.rr.com. Below is the text from our company technician who looked into this. Spectrum really needs to fix this issue, as it blocks emails from random people at random times (frustrating).

“I’ve reviewed the email you forwarded, as well as researched the issue online. It appears that this is an intermittent issue affecting multiple people. Specifically, it is manifesting on people sending email TO @.rr.com. They are all getting the same error, and it has happened in a few areas in the northeastern US and I’ve found at least one other person experiencing the same issue in the Charlotte area. The issue only seems to occur when sending FROM Office 365 email addresses.

The consensus seems to be that the error is on Spectrum’s side. Specifically, the error reported stems from what is known as a failed SPF check, which occurs on the recipient side, not the sender side. It also explains why you are having this issue while some of your colleagues can successfully send to this recipient—the same thing has been reported by others, that it seems to be random and will affect some users and others will not. The first reports of this that I can find are from October, which tracks with responses from Spectrum that they have been doing some reconfiguration work on their mail servers.

Unfortunately, the end result of this is that there really isn’t anything to fix on your computer or with Office 365; the issue is on Spectrum’s mail servers, and until they resolve it, it will likely continue intermittently.”
