What is the black dot next to my mail account
I am unable to receive email from my iCloud account. Next to the account name a black dot with a squiggly white line in it has appeared and I cannot delete it?

That means it is not connected to the email server.
If you click on that, you can have it try to go online.
If it fails, it may give you a hint as to why.
