Hi, thanks for taking the time to view this post, i just hope someone can help.
I have recently had to reinstall my Op system (WinXP) and i have now noticed that i cant send emails via Thunderbird

, but i can still receive
I think i have setup Thunderbird correctly, i followed the instructions found on the Yahoo, Options, Pop3 Forwarding config webpage. Whenever i try to send a email i get the following error message from Thunderbird
Sending of message failed. The message could not be sent because connecting to the SMTP server smtp.mail.yahoo.co.uk failed. The server may be unavailable or is refusing SMTP connections. Please verify that your SMTP server setting is correct and try again.
It looks like to me that the SMTP setting is incorrect but i've triple checked it. A friend of mine is also having the same problem on the same setup as me so it leads me to believe that its something to so with yahoo.co.uk mail accounts.
Any advice will be much appreciated - please let me know if you need any other details.
