[Gary VanderMolen]

The key part of the error message is "relaying not allowed."
When you got that error message, was your Internet connection coming
from Cox?

Try this:
Go to Tools, Accounts, select that account, Properties, Servers.
Enable the "My server requires authentication" option. Click OK.
Now try sending.

 

[Sam Hobbs]

See:
http://social.technet.microsoft.com/Search/en-US?query=0x800CCC79 relay&ac=8

There are a few results there, but they seem to all be for Outlook and
Exchange Server and such. It might actually be a problem with the server,
but that is only a guess based on the results from above.

Nope. Like you, we're all to stupid to have a computer.

Nope. No one has figured it out. How could Microsoft release a mail

Seriously, if you need help, right-click on your error message, copy,
then paste it into a reply here.
We can't do much troubleshooting without the complete error message.

You aren't using Yahoo, so your problem is completely different from the
OP's.

Change the SMTP port to 587 and make sure: My Server Requires

If there is no recipient, then Windows Mail will complain that the message
cannot be sent. It won't even try. So the AV problem is the likely one.

Gary. Thank you very much. This advice fixed my problem.

The key part of the error message is "relaying not allowed."

The server is complaining because you are using a From address that is not
associated with that account. When using a different From address, you must
first verify that you own that address. You may have tried that procedure,
but it did not 'take'. Try again:

Subject 'Fw:Turbo Tax- Instant $10 Savings - One Week Only!'
Server Error: 550
Server Response: 550 5.5.0 <> missing or malformed local part
Server: 'smtp.comcast.net'
Windows Live Mail Error ID: 0x800CCC79
Protocol: SMTP
Port: 25
Secure(SSL): No

I can still send and receive e-mails, but I cannot get rid of this error
message- every time I try and sync my mail, it comes up and I cannot
delete
it. Driving me crazy- any suggestions?

:

Port 25 is not recommended for that mail server. Change it to port 465
with SSL. The correct settings are documented here:
