Sorry for that.
My problem is I cannot send email from IE or Outlook
but I can from this groups and this is what I get when I send:-The message
could not be sent because the server rejected the sender's e-mail address.
The sender's e-mail address was '. Subject 'Test',
Account: 'BT', Server: 'mail.btinternet.com', Protocol: SMTP, Server
Response: '530 authentication required - Your email could not be sent. To
fix this you must make a simple change to your email (known as SMTP
authentication). For advice visit www.btyahoo.com/smtp or call 0800 328
9968', Port: 25, Secure(SSL): No, Server Error: 530, Error Number:
0x800CCC78

I ohave been able to send before and this problem has only started within
the last and I have don't use Google only BTYahoo and I have turned off
my anti virus
but it is still happening, I don't understand.
