I've been using this for a couple of months now, and it's been working great.
One problem - I have had a number of AOL spam complaints due to lazy AOL users who would report these mailings as spam instead of letting me know that they'd like to have their accounts deleted. I real PITA.
Is there any way to deselect AOL email addresses (or any email addresses for that matter) using wild cards? That would be great to add as a modification. In the meantime, I've had to shut this off.
