Xfinity won't send email either from website or from Mac's Mail program

Hi, all of a sudden my email won't let me send any messages.  It won't send either online or via Mac's Mail program.  What should I do?

Thanks for any help.

Same problem here.  Can't send from either Mac Mail or Xfinity web site.

 

From Xfinity web site I get one of:

 

    "The connection to remote server smtp.comcast.net timed out while awaiting the response. Please try again later."

or

    "An error occurred inside the server which prevented it from fulfilling the request."

Same here. I can recieve emails using mac mail but i can't send. I keep getting:

 

The sender address was rejected by the server smtp.comcast.net

 

The server response was: Authentication required

 

But when i go to connection doctor it links up. I don't know what to do. I have quadruple checked my passwords. 

 

Using comcasts website i can send just fine, so at least i have that.
