I continue to have problems with my outbox in Mail wenn using my iCloud account. I've controlled everything, it seems to be online. I do receive mails, but I can't send them.
I only have this problem on my Macbook with MacOS BIGSUR, not iPhone or iPad.
Does anybody have a solution for me?
MacBook Pro 15″, macOS 11.4
