I've got a customer who uses email addresses that they get along with their Hosting package, they been using the same hosting and emails for at least 5 years. Within the last two weeks they are getting dozens of bounced email's messages that they are sending that are work proposals from recipients with Verizon.Net and Aol.Com email address.
The return message is:

I've talked to their hosting provider and they basically said "This is not our problem"; I filled out the Aol whitelist request early last week and nothing has changed as far as I can tell; I emailed [email protected] and asked why the emails are being bounced and no response after almost a week; I talked to Verizon who gave me an Aol support number and I talked to Aol and they said "You are not our customer, there's nothing we can do to help you". I told my customers that basically the people who have the email addresses that we can't send to are the ones that have to complain that the emails they are being sent are bouncing and those people say "I'm getting email from everyone but you so why should I take my time to call Aol for what seems to be your problem?"
I can't help but wonder if this has something to do with the migration of Verizon.net emails to Aol.Com.
So here's the thing, what can I do that I haven't already done? How can I get this fixed?
