 Also, just curious, but do you have problems with the forward
and reverse DNS of you mail servers not mapping together (ex. mail.dailykos.com
maps to 69.9.164.210, but the reverse of 69.9.164.210 is faye.voxel.net - in
particular do you have problems with ISPs like AOL?).

I'm pretty sure AOL just requires a valid reverse DNS. They definitely don't require that the reverse DNS and the MX or the HELO match. Doing that would block a huge amount of legitimate mail, since many, many mail servers handle mail for multiple domains.
