All emails from my company email server to AOL getting rejected

[BCinSC]

We're a small software company with some clients and investors that use AOL. We tried to send an email to them, and they ultimately (like days later) came back undeliverable. I tried sending one to my Mom's AOL account, and it also bounced back, yet when I use my gmail or Comcast account, they go through fine. No email to other recipients is being block/rejected. I can't imagine how we might have been blacklisted, very rarely sending any email, especially bulk (if you can call a dozen or so recipients "bulk") and have a high-end firewall, so I doubt any company machine has been zombied into a spam mailer (no record of such in the logs). Is there somewhere I can find out why AOL is bouncing us?

If you see any type of error code in the undeliverable message you might want to try to look it up here http://postmaster.info.aol.com/errors/

If you send from www@yourdomain.com or apache@yourdomain.com they will block it. I'm a netadmin at a publications/online education company and we were recently informed of this.

The most common way to get a mail server rejected by AOL is a bad reverse DNS/MX record lookup when they check who sent the email. Do you have a static IP? We've had to call the postmaster department at AOL a couple of times with customer issues, and they were actually helpful. It helps to have a rejected message available so they can decypher what has gotten you rejected.
