Yesterday I upgraded from Catalina to Big Sur on my 2018 Mac mini.
Prior to upgrading to Big Sur, sending and receiving mail on Apple Mail worked flawlessly. However, after the upgrade IMAP mail times out when trying to log into GoDaddy's IMAP server.
I have spoken with GoDaddy and they assure that absolutely NOTHING has changed at their end.
I am using Port 587 and "Use TLS/SSL" is checked.
What has changed in Big Sur?
I'm having this issue too.
I've been on the phone with GoDaddy three times today. I'm pretty sure it's not on their side. I've been on Apple chat for the past two hours trying to trouble shoot things. Nothing. I don't have anything fancy installed like Avast or Little Snitch (not sure what that is, but maybe I should look into it.)
Apple doesn't seem to know. They keep wanting to blame it on the provider, but it's not the GoDaddy side if email works 100% through their portal.
AND I can't send emails from my any of the desktops in the house, or iphones.
PLEASE Apple, figure this out and post an answer.
Try uninstalling your AntiVirus software.
Also, if you have LittleSnitch installed, try uninstalling it as well.
Then try downloading your email.
Thank you for your reply. I have Malwarebytes for Mac paid subscription for several years.
Happy 2021 stay safe.
