January 7, 2020. All of a sudden today I cannot send emails. They show up as sent but are not received. I have tried my Mac, iPhone and iPad and it happens on all three. It happens doing email directly in xfinity mail, outlook or with the Apple mail. Is Comcast having a problem or has something changed?
If @CCAntiSpam or another employee doesn't reply to your message here, Comcast Security Assurance should be able to help. You can reach them at 1-888-565-4329 (from https://internetsecurity.xfinity.com/help/report-abuse/). Note that this is NOT one of the general customer service numbers.
The first-line reps there are sometimes not very helpful, so you may need to be persistent and keep at them until you get a satisfactory answer.
@ranger26 Please try again in about 10 minutes.
