Why can I no longer send eMails ?
My Email suddenly stopped allowing me to send .. I made no changes .
iMac 21.5″, 10.13
Apparently there is no way to know why this happened. I will assume that the computer's email app is not sending the correct user ID or password to the email service provider's web site and the connection to it times out. Open your email app and carefully check the user ID and passwords that are shown in the Preferences section. Correcting them should fix the problem. In the alternative, you can delete the account in the email app and then create a new account.
