Cannot send mail

[Puzzled]

This seems to be a common problem. I have been able to receive and send
e-mails until a few days ago. Now cannot send. These are my settings
incoming mail server is a POP3
incoming: mail.comcast.net
outgoing: smtp.comcast.net
port: 587
authentication not checked

Authentication MUST be checked.
