Unable to send email, server temporarily not available
I have multiple emails in the queue to send with the following message. I logged into web interface and was required to change my password.
How do I resolve this issue?
(host smtp.comcast.net[68.87.20.6] refused to talk to me: 421 resomta-ch2-10v.sys.comcast.net resomta-ch2-10v.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available)

That phrase usually means that you have a program, app, or device that is trying to send mail using an invalid UserID/password. If @ComcastSPAAbuse 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.
