Can't send email to AOL?

This week I had a client that couldn't send email to AOL members. Where better to go than check out their pages. Their Postmaster site is actually pretty good at explaining what you need to do.

Short point of our story is a telnet to their mail server determined our IP was being blacklisted although it's on a T1 and not a spammer in any way. A quick call to their Postmaster support desk fixed the problem.
