email 550 error for known addresses
Today we've recently started to get emails that wouldn't send and received a permanent failure reply from the Comcast server. This has occurred when sending emails to addresses we've been emailing for years. Normally apple mail is used to handle emails. When attempting to send to those addresses from webmail it gave us a 550 - 550 5.1.1 error. Though out the day more and more addresses in different domains are unreachable. We also learned that a couple of people emailing us have gotten a similar message. Other emails are able to be sent and received just fine.

Thank you for reaching out and creating a new post. I understand you're starting to get errors when emailing an address you've contacted before, and you're getting reports that others are having issues emailing you as well. I can see how this would be confusing when these are known addresses you've used before. You stated that all other emails work fine. To confirm, are you able to email only some known addresses and not others? Are these emails coming from different providers or a specific business email address, for example?
