They are good. The Bad Guys, I mean. They create official looking emails that look exactly like your banks email. But, of course, since they are 'Bad Guys', any info you give doesn't get to the bank. Well, eventually it does when they use YOUR info to get YOUR money.
Here is the latest example I received last week:
Bank Of America Alert: Online Access Suspension Message

(note the official logo coming directly from the bank's website)
Email block of mail from our servers to AOL has been removed.
I had to give them a call, and register the servers with AOL. They were pretty responsive, though it's odd that it takes a couple days for them to remove the blocks. Once registered, supposedly we will be notified by AOL if there is a reported issue, instead of them just blocking us.
Brian,
Thanks again for your outstanding help. You obviously know this stuff cold.
