Can't send e-mails

[caz54]

Hi, Can anyone help?
Every time I try to send e-mail I get the following error message.

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Subject 'Fw: Twins - hilarious!', Account: 'mail.btinternet.com',
Server: 'mail.btinternet.com', Protocol: SMTP, Server Response: '451 See
http://pobox.com/~djb/docs/smtplf.html.', Port: 25, Secure(SSL): No, Server
Error: 451, Error Number: 0x800CCC0F

I can still receive mail.

Many thanks

Further to previous e-mails`Cant send e-mails` I have tried to send the same
attachment to 5o clubs and I receive the message `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 'wilcot'. Subject 'Re: Umpiring Training
Courses', Account: 'mail.btinternet.com', Server: 'mail.btinternet.com',
Protocol: SMTP, Server Response: '453 Wrong format for recipient email
address', Port: 25, Secure(SSL): No, Server Error: 453, Error Number:
0x800CCC79`
Now my question - will the other clubs have received the mesage as it does
not appear in the `Sent box`

That type of error is usually caused by interference from a non-
compatible antivirus program. Which antivirus are you running?
As a minimum, email scanning in the antivirus must be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

If turning off your antivirus email scanning function does not resolve
your problem, consider upgrading to Windows Live Mail, because it
is less prone to suffering bad effects from overly intrusive antivirus
programs: http://get.live.com/wlmail/overview

Email scanning in any antivirus must be disabled, for reasons
explained here:

Like it says, "wilcot" is not a valid email address.
That error message came from the mail server. Depending on that
mail server's policy, it is not clear if it would go ahead and send that
message to the remainder (correct) email addresses. All you can do
is call and ask one of the other recipients.
