Paypal look alike Fradulent Emails - Beware

This is an experience that happened to me today. I was planning to sell my camera Lens and buy a bigger lens. I had put the Ad in Craigslist. One guy responded and mentioned that he would do the payment through paypal. Since it was paypal, there was nothing to panic for me. I got a Paypal confirmation from him today morning, mentioning that I have received the amount and I can go ahead and do the shipment.

Couple of things didnt look normal in the mail
1. The Shipment Address was Nigeria. The guy had mentioned that he is gifting to his fiancée. I thought this guy to be some merchant and he didnt want to mention it.

2. I wanted to login to my paypal account and wanted to see any amount in my account. I was searching for a link in the mail. Normally, such mails will have a link that points to my account and once I provide the password, I would be taken to my account. But unfortunately, there was no link to paypal.

3. I opened paypal site in a seperate browser and checked the procedure for such kind of payment. The procedure said this: Once the buyer sends the money, the amount will be shown as "Pending/Hold" in my Paypal account and once I do the shipment and provide the tracking number to Paypal, the amount will be credited.

4. My mail id was highlighted. When I clicked the link, it opened "Compose message" window and the To Address was some wierd yahoo mail address.

5. I called PayPal Customer Care and asked them whatz happening. I provided them the buyer's email address and they told me there is no such account and it is fraud. Had I not taken steps to ensure the accuracy, I would have lost around $300 in this transaction. They asked me to forward the mail to spoof@paypal.com and they would verify it and take action on it.

The Paypal confirmation mail was hand drafted by some hi-tech thieves and unless you look into it very very closely, you cant make out any difference.
I got the mail from service@paypal.com. But actually that is the name and the mail id was paypalcustomerservicecentre@ukaccountant.net, which is not a Paypal ID.

I havent done such kind of transaction in Paypal and this is a eye opener for me. It may be a eye-opener for you as well. So beware of any email especially related to shopping and money.
