I believe (haven't tried it yet, but i plan to) that Mozilla's Thunderbird email client (Similiar to  Outlook Express; made by the people who brought you the Firefox browser) will let you check you free htmail accounts.\n\nI've read this at more than one place, but I've yet to try it.

Most email clients has option to see headers where you can see the IP address of the sender, but this does not lead directly to to exact pc where the email came out from, it may lead you back to the proxy server...ISP...etc

You can't an email address is not tied to an IP address.  Anyone could login and use email whether it's web based or not.

Yes, hoax.  There is currently no way for Microsoft to track your email.  And why would they give away money?

Open the Full headers of that email. You would get the IP of the machine that the email is sent from.

What is the mailing address?

Probably a "spoof" address, it does not resolve.  there is no such host, nor user name.  I think whoever sent this is trying to portray themselves as a domain admin though, as the "master account on a unix system is referred to as "root"  and it looks like they want you to think its the uk, but the domain is not properly formatted for that.. the proper way would be "user@domain.co.uk" if it were from the brits!\n\nwhats going on?  Need some help?\n\nIf you can post the whole header of the email I can track it from that.

Contact the email provider and have them check their server. Most likely it is a domain problem.\n\nAlso, run an anti-spyware program to check your own computer
