It is proven now, all the e-mails sent to you cannot be trusted. Even if you have an anti-spam software, some fraudulent emails can still reach your inbox. So just delete mails from people you don't know or trust.
even one of my friend experienced this bad situation..
actually he received this kind of mail through his website.
his whole lots of work in creating the website got spoiled because of it..
I think in forums their are almost 90 webmasters out of hundred and i don't expect this that any webmaster get fooled in such things , even i receive $ 10000000 lottery wining and other such emails which makes me also dreaming but don't believe on such mails .
Ive had quite a few emails like this, claiming to be hotmail asking for my password or similar. I always stay away from them and just delete them as quick as possible.
