Checking an email address

[Redneck Rocket]

Have recieved an email through my website which purports to be a genuine enquiry but for some reason I smell a rat. Is there any way for me to find out when the email address was created? If it has only been in existence for 24 hours I can be pretty sure it's one of our competitors trying to suss us out.

Cheers,

RNR

Stick the domain in www.dnsstuff.com that should tell you everything you need to know. If it's a Hot/G-mail type address then you're stuffed.

It's a Yahoo.
