Comcast SMTP outbound Email not working [smtp.comcast.net]
My ISP is Comcast / Xfinity, connected by SB6190 modem and Netgear R7000 router, neither of which has changed recently.
Every night at midnight the Router is configured to send its logs to me. It actually sends from one comcast.net address to a separate one [I have 3 routers configured this way -- by separating the sending addresses I can easily filter / file the incoming "logs" on my computer]. Yesterday, mid-day, I logged into the router and discovered that the email was not sent the previous night. I double checked (and corrected the "sending" email address configuration) and manually sent the logs at around 10 pm. In response, the router logged:
[email sent to: <my-email-1>@comcast.net] Wednesday, Dec 07,2022 22:05:04
[email sent to: <my-email-2>@comcast.net] Wednesday, Dec 07,2022 22:05:03
*NOTE* I'm using <my-email-n> in place of the real addresses.
2 Hours later, at midnight, when the "automatic" send is supposed to happen, the email failed. The router logged:
[email failed] resomta-h1p-027915.sys.comcast.net resomta-h1p-027915.sys.comcast.net Excessive fa Thursday, Dec 08,2022 00:01:02
[email failed] resomta-a1p-077053.sys.comcast.net resomta-a1p-077053.sys.comcast.net Excessive fa Thursday, Dec 08,2022 00:01:01
NO CHANGES HAD BEEN MADE TO THE ROUTER IN THE INTERVENING 2 HOURS. NO COMPUTERS WERE ACTIVE.
I can *RECEIVE* email via POP just fine. But neither I nor my partner can send email. I've tried more than once to restart the cable modem and the router, but it always seems to assign me the same IP address. My partner and I are both using MacBook Pro (M1 Chip) running MacOS Monterey (12.6.1) with Apple Mail 16.0. I have no problem sending SMTP email via my apple-supplied .mac address.
PLEASE PLEASE PLEASE, someone respond. We are not trying to "spam" anyone - we're just trying to send simple text-based emails.
I have been a loyal Comcast subscriber for nearly 20 years. I'm seriously beginning to question my "loyalty"

"Excessive fa" in the error message might be "Excessive failed authentication". That phrase usually means you have a program, app, or device that is periodically trying to send or sync email using an invalid UserID/password. If the number of login attempts exceeds the mail server's threshold it responds with that error message. The fix is to locate the offending program, app, or device and correct its settings.
Please see https://forums.xfinity.com/conversations/email/cannot-send-email-0x800ccc0f-connection-to-server-interrupted-or-0x800ccc67-esmtp-server-temporarily-not-available-message/61b28270f06968168603033a?commentId=61b7a0b5f069681686037267 and the other messages in that topic for additional information.

I am having the same issue with sending emails to the exact same email address that I have used for years. This even happens when i am blind coping myself which is my comcast email address. Nothing has changed in my settings at all. I am using the comcast gateway modem/router. The only change that was made was Comcast did some type of maintenance to upgrade cabling. I called comcast and received a run around from an agent that was clueless. He actually said he was making changes and it would take 3 hours to see if it works. When I questioned him, he had no answers. So basically he was trying to get me off his phone knowing when I called back I would get someone else. This is not acceptable as i have been a customer for over 20 years.

As you see, my comcast email was tagged as spam.
Something has to give. This is the address that I am using for business. Any help would be greatly appreciated.
