Cannot send myself an email on iCloud acount
I get this pop up saying after sending myself an e-mail:
Verify that you have addressed this message correctly. Check your SMTP server settings in Mail preferences and verify any advanced settings with your system administrator.
The server response was: <cpe-xxx-xxx-xxx-xx-socal.res.rr.com[xxx.xxx.xxx.xx]>: Client host rejected: Access denied
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.
Sending from: xxxx xxxxxxxxxxxx <xxxxxxxxxxxxx@icloud.com>
