Cannot send emails on iPhone from Mail
I cannot send emails on iPhone from Mail. I can receive mails and mail on iCloud works fine both ways. Also there are no issues on my MacBook.
I have done the actions listed in Apple’s support and in existing threads on the topic, to no avail.
See screenshot, it is in Swedish but I assume you get the gist of it. I am on iOS 15 but issue was present before upgrading from 14.8
iPhone SE, iOS 15
