Email Black Listing?

We have certain domains we send email to, which in a few days we will get back as undeliverable because they timed out. We have tried directly typing in the address and also via Reply in an email they sent to us. This is all Ecomm communication that we're dealing with. It's vitally important for us because these are our customers and/or potential customers who are contacting us through these domains but we are unable to even reply back without getting bounced.

Does these events mean we may have been blacklisted by that domain? Specifically the three domains are aol.com, rr.com and cs.com

Now we do not send out ANY email's outside of normal Replies and Correspondence. We are totally WHITE hat people here (Sorry, you black hatters).

If we have been blacklisted, how can we find out and how do we get it changed?

Happens to me a lot too. I've found it common with AOL, hotmail, and yahoo.

I think you might have to "pay off" these guys so they let you send email to them.

Are you sending the emails out with html formatting?
If so, as a test try sending out as plain text.
