Vista - Cannot send but can receive emails

When I click on send and receive, my emails will not send from my outbox.
The error message I get is : -

An unknown error has occurred. Subject 'Order of Service - Mike Jackson',
Account: 'pop.ntlworld.com', Server: 'smtp.ntlworld.com', Protocol: SMTP,
Server Response: '421 aamtaout02-winn.ispmail.ntl.com connection refused from
[81.146.68.152]', Port: 25, Secure(SSL): No, Server Error: 421, Error Number:
0x800CCC67

Any ideas?

i'm having the same problem recently. tried adding another email account but
it's the same outcome. i troubleshoot it using windows mail but to no avail.
i thought i was the only one having this problem. pls let me know if you're
able to solve it yourself. good luck.

Make sure you have send authentication enabled.
Go to Tools, Accounts, select that account, Properties, Servers.
The box for "My server requires authentication" must be checked.

If no improvement, is your Internet connection being provided by someone
else besides Virgin Media?

Do you get an error message when you try to send? If so,
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.

found the solutions to the problem thanks to gary vandermolen.

basically, you need to use port 465 outgoing and 995 incoming and make sure
those boxes are checked. here's a link that might explain it a lil better
than i do. good luck.

it freakin' worked! thanks bo. .

Amazing how well it works when you follow the mail provider's instructions.
