OK I used to have Charter internet until recently a new local ISP bought them out in my area. For many years I used Outlook Express and then Windows Live mail with no issues while with Charter.

So a couple of days ago the new local ISP company took over Charter and I had to change my email address to the new ISP. I followed their directions exactly that they have posted on the internet. I then tested my email.. I found out that I can recieve email from anyone but I can ONLY send to others who are on the same ISP that I am on. I can not send an email to AOL addresses, yahoo, hotmail or any others, only my local ISP. This is the error I get.
"Subject 'Test'
The message could not be sent. The setting for your outgoing email server might need to be configured. To find the server settings for 'tech***@yahoo.com', please contact your email service provider.
Subject 'TEST'
Server Error: 473
Server Response: 473 tech***@yahoo.com relaying prohibited. You should authenticate first
Server: 'smtp.hargray.com'
Windows Live Mail Error ID: 0x800CCC79
Protocol: SMTP
Port: 25
Secure(SSL): No"

So I called my local ISP tech support and we stayed on the phone for about an hour with the same error message over and over. She made it sound like it was on my end, but I think it is with their server. I have set EVERYTHING to their specifications over and over and I still get the same error over and over. EXCEPT if I send an email to someone on THEIR network then it sends fine, a little slow, but it will send. I don't get it.. I have erased all Charter email settings from Windows Live Mail.. I hooked two different computers up both with live mail and Outlook and I even uninstalled my anti-virus and disabled my firewall to see if that would work. Also I checked for malware. Nothing!

ANY ideas?? HELP!!! Oh and I can sign onto their web mail client and no issues, but I hate web mail.

Check to make sure you have outgoing authentication for the SMTP server selected.

Behind every good computer... is a jumble of wires 'n stuff.

According to their directions that does not need to be checked. I have checked it off just out of curiosity and it still came up with an error. I can send emails to other people on their (Hargray.com) all day long, but not other email addresses that are outside of their network.

You can try changing your default "Outgoing Mail(SMTP)port" from 25 to
587. You need to open the properties on your Internet Account in your email program. Go to the Advanced Tab and under Server Port Numbers you should see it being 25 change it to 587. I have fixed a number of folks "out going mail" by changing to that port.

also make sure there is a check under "Outgoing Mail Server" in the
"My server requires authentication" box as stated in the above post.

I appreciate the help.. I tried what you said and it came up with another error so I just gave up. I don't understand why it will send email to people on their network, but not others. This is why I think it has to be on their end. I fixed (patched)the issue by having everthing forwarded through G-Mail. So that is working fine for me.. Thanks again!

My bet is their end also.

Check and make sure there is not a dash after smtp instead of a period.
On my local brighthouse network they use a dash between both the POP and SMTP and server the dot.xxxx.com. This drove me nuts at first trying to find the error of my ways.
