certian contact of mine, but the strange part is that i am able to send email
to all of my other contacts

heres what the error message looks like when i try to send to this contact

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 '___@___.com'. Subject 'send reply',

I would interpret that to mean that you are trying to use the Comcast SMTP
server while connected through some other ISP.
 
well then how can i fix it?

It would have helped us to diagnose the problem if you had not
wiped out the domain name portion of the destination email address.

According to your ISP:
http://www.comcast.net/help/faq/index.jsp?faq=Emailtop17686
you are supposed to be using port 587 instead of port 25 for the
outgoing (SMTP) mail server. When you change that, also make sure
you have "My server requires authentication" checked.

I didn't need the username part, just the domain.
As I suspected "youkontimbers.com" is not a valid domain name.
That's why you got the "destination not valid within DNS" error message.

gary,
I've been reading quite a few of your posts and hoped you could help me with
my outgoing mail problem.

Here's the facts.
New computer(dell laptop) with windows home premium vista.
Like many here, cannot send outgoing mail. Here's all the pertinent
information.

Error message for outgoing mail
your server has unexpectedly terminated the connection. Possible causes for
this include server problems, entwork problems,or a long period of
inactivity. Subject
"test", Account: 'cindy Perusse:, Server: 'smtpauth.earthlink.net',
Protocol: SMTP, Port: 25, Secure(SSL): no, Error number: 0x800CC0F

Other information for you. I've been using comcast with earthlink mail and
no problems on my windows xp program.

I have "NOT" installed any anti virus software yet.
My server information has "my server requires authentication" checked in the
box.
Outgoing server port is 25

My computer is connected through a Linksys router. Again the other two
laptops on this router give me no problems with Windows XP.

Hope this is all the information you would need. Brand new computer so plan
on calling Microsoft or DEll.

Thanks in advance for any help you can give me Gary.

Thanks for including such detailed information. It is very helpful.

Let's start with the most likely cause.
Change the outgoing port number to 587 (instead of 25).
EarthLink supports both port numbers, but 587 will work under
more circumstances.

If that didn't fix the problem, try this next:
There is a new TCP tuning feature in Vista which is
not compatible with some servers.
a. Go to the Vista start menu and type cmd
b. The search results will display a program titled cmd
c. Right-click on the link and select "Run as administrator"
d. type "netsh interface tcp set global autotuning=disabled" without
the quotation marks
e. Test your POP account and see if you can now download your mail.
f. If nothing changes, re-enable the autotuning feature by typing
"netsh interface tcp set global autotuning=normal"
Note: Instead of steps a & b, you can also use the shortcut
for Command Prompt, if you are more familiar with it.

Let us know if any of this was successful.

according to this webpage, you need to change the outgoing port to 587

http://kb.earthlink.net/case.asp?s=st=872,e=0000000001509110750,k=9632,sxi=11&article=21833

port 25 only works if you are on Earthlink's network
