Yes I get about 1-2 a day. They seem so real. Some are an item question, money I sent or recived, or something wrong with my account and need to verify it, etc.
First off both eBay and PayPal will never ask you for your login info. All eBay messages are in your 'My Messages' folder when you log in to eBay.
One quick check is to just put your cursor over the link they want you to click and see the address at the bottom of your browser. Always look at the very beginning of the URL. Anything after the dot com does not matter. Some of the really good ones will include ebay.com or paypal.com somewhere to the right of the dot com to fool you.
If you have any doubts always log into your account using a seperate browser window your normal way and check for problems.
I like showing some of the better ones to my friends just to show them what not to do.
