Hey, rose1923.
I see that you're experiencing a problem sending email using your @icloud.com email address. It keeps getting rejected by the server, and I'm glad to help.
Mail server settings for iCloud email clients -- Make sure that your settings are still correct.
Get help using iCloud Mail -- If your settings were correct, review the information and apply any pertinent steps to correct the issue.
Let me know how that goes, and take care!
