iCloud Mail and Comcast fail to send mail

Hi gang. I cannot send email in Apple Mail, Sonoma 14.4.1. My WiFi ISP is Comcast. My Google Mail's POP server account sends fine but every time I try to send via my iCloud account I get this error message. It looks like Comcast is trying to send via one of their SMTP servers and not iCloud POP server. I have to use my iPad, which is also on Comcast WiFi, to send mail. Would anyone advise?

Apple mail with Comcast - anyone else having the same problem? I have 3 Apple mail email addresses that have been setup and working with no issues for years. As of around November 15 my main email address stopped sending outgoing mail. Webmail (Comcast mail using a browser) and email using my iphone have no problems. Other 2 email addresses still work for incoming and outgoing email and Apple mail. I am using an iMac. Does anyone else who uses Comcast as a provider for email experience the same problem? I could not get any help from Apple or Comcast. Nobody can explain what I should do based on the error message I get when I try to send an email using Apple mail from the email address that has a problem ("The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again"). Nothing was changed on my end for years. I did change my password for this email address in Comcast, in Apple mail on on my iphone. I knew that this will not be a fix, and it was not, but I tried. If anyone else has the same issue, please let me know.

Cannot send mail Cannot send mail ” The connection to the outgoing server ‘apple.smtp.mail.yahoo.com’ failed. Additional outgoing mail servers can be configured for mail accounts in Settings>Accounts .” I'm completely lost. This just happened out of the blue and I do not know how to fix it. I try and follow the prompts, but everything looks normal to me. What do I need to do? Thank you in advance.
