Use the Connection Doctor...

Use Connection Doctor in Mail on Mac - Apple Support

check your SMTP server settings

Your link on connection doctor was obtuse at best. found thus more helpful Where is the "Mail Connection Doctor" in … - Apple Community

I think I understand that you were trying to point me to a guide on Mac Mail. thanks. bu I have been here since 10.1

The connection doctor give me a green on smtp.mail.me.com. which I am allowing the application to automatically control.

If Connection Doctor is showing green for you on that specific Account SMTP, then I would query your email provider if there is some temporary issue on the server side— this would be out of your control...

Green light indicates both password and SMTP server setting are all correct.

or simply try at a later hour /day if the issue resolves.

If your issue is isolated to this one mac—

You can quit Mail, relaunch it holding the Shift key down, and compare your results.

if it is a problem accounts on that Mac—the go to way to sort things out is to delete the account(s) from the Mail.app, then add it back.

Remove email accounts in Mail on Mac

Remove email accounts in Mail on Mac - Apple Support

Add email accounts in Mail on Mac - Apple Support

Add email accounts in Mail on Mac - Apple Support

Note—

IMAP accounts stay on the server, so no local loss, when you re-sync

POP accounts download and remove from the server—therefor save your inbox/sent box if you want them

“On My Mac" is just that, local folders you created and moved mail into. So no loss

I Neve said it was a spread or load problem. just a Sonoma. Thanks for the contact link. first useful piece of information

Yes, you indicated that things run ok under Monterey but not under Sonoma. Ordinarily that is indicative of something installed and running in the background that is compatible with Monterey but not with Sonoma. The solution is usually to update that item to a version compatible with Sonoma or uninstall that item. Not knowing what is installed, it is hard to say.

You can download Etrecheck, a free diagnostic program. After running it, post the output here using "Additional text" button below. Etrecheck has instructions for the specific steps to follow, it is basically like copying and pasting. Etrecheck's output anonymizes the information so it shows what is installed but does not reveal any identifying information. You can check that before posting the output here. Etrecheck is open source software, by the way. When you post the output, a slew of experts (I am an informed user but by no means an expert) will try to find the culprit for you.

I sort of doubt that the problem is with Sonoma because

• You are using Mac mail, it should be compatible
• Sonoma is fairly mature (it will be replaced soon, actually), updates have been made to eliminate most "bugs"
• Hundreds of thousands if not millions of Sonoma users are sending/receiving emails constantly, including many using comcast

So the challenge is finding what is unique to your setup and could cause this. Any third party security tools, anti-virus, "cleaning" tools (CleanMyMac), third party VPN, optimizing tools, network monitoring tools, and the like are immediately suspect because those things often work under older MacOS versions but stop working with an updated Mac. Etrecheck will highlight items like those for attention.

That error message references comcast, which I am guessing is your internet provider. Is there some issue with comcast, or some security setting or utility installed on your Mac or provided by comcast that could be interfering. Also, elsewhere you said "My other accounts are working fine" but above you said all email accounts are affected.
