Here is the message I get from Comcast every time I try to send an email
using a distribution list.

An unknown error has occurred. Subject 'Fw: Florida Power & Light', Account:
'mail.comcast.net', Server: 'smtp.comcast.net', Protocol: SMTP, Server
Response: '550 5.1.1 Not our Customer', Port: 25, Secure(SSL): No, Server
Error: 550, Error Number: 0x800CCC69

Regular messages send just fine. Distribution lists I use have a range from
only 5 addresses to 58?
 
I tried what Gary suggested and now I get:
The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '(e-mail address removed)'. Subject 'Fw: Florida
Power & Light', Account: 'mail.comcast.net', Server: 'smtp.comcast.net',
Protocol: SMTP, Server Response: '550 5.1.1 Not our Customer', Port: 587,
Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
 
Comcast says they don't have a customer with the email address
(e-mail address removed). I tried it and got the same error.
Are you able to send to yourself? If so, your sending is working normally.

You're very welcome. Thanks for reporting back.
I assume you are talking about the bad (e-mail address removed) address.

Note: The custom here is to reply to the response rather than to your
own original post.
