Server busy when sending email from Mac, Big Sur
when I send an email I get a pop-up that says " the server is busy and message could not be sent to icloud", but the mail is in the sent box, so I figure it was sent. why is that message popping up all the time? it also says "The imap command APPEND to send failed. I just got this mac book air a few weeks ago, never had this problem with the old pro laptop.
