Earthlink imap outgoing mail will not send from Mac
I am unable to send mail from my earthlink accounts from my Mac. I have confirmed that all the settings in Mail are correct. I think the issue is with the OS or machine because I can send without problem from iPad and iPhone, and the Webmail functions fine. I m running OS 12.1 Monterey. I receive mail from the accounts without problem. Suggestions about how to fix this?
