If you receive a bounce message when you try to send email to AOL and you are on a shared hosting plan forward the bounce message to support@appliedi.net.
Another helpful part of the email to forward to us is the email headers. For instructions on copying headers, here’s a helpful link: https://www.spamcop.net/fom-serve/cache/19.html
If you are a dedicated hosting or VPS client please contact the AOL postmaster http://postmaster.aol.com. You may want to setup a feedback loop with AOL so you can monitor any complaints generated by your server.
