Unable to send Emails but can receive them. Message states 'smtp server at 212.74.114.62: port25 error 554. received when trying to send. Have set up Email account on wife's laptop on same settings and can send with no problems. I am broadband with Tiscali.co.uk using Belkin router and Belkin adapter in a slot drive. My wife uses the same router but with a belkin usb adapter.
Tiscali technical ( who I find useless and less informed than myself) asure me its not their problem. I have also contacted Sony Vaio who informs me its not a Windows XP or Outlook Express software problem. Can anyone help

Double check the smtp settings and check if authentication is required.

Thanks for response but have already carried checks suggested but I still have the problem.

There is a box in Outlook Express where you can make it more functional but less secure. I had to use it myself as I was getting errors trying to send mail. TOOLS/OPTIONS/SECURITY
