AOL uses SPF for maintaining the whitelist. AOL will begin using SPF records to maintain our whitelist in the near future. It is best for all organizations on AOL's whitelist to begin listing and maintaining (up to date) their SPF records so AOL can maintain accurate and up-to-date whitelisting of that domain's IP addresses. We will provide additional information in conjunction with our whitelist information pages.
If you want guaranteed delivery of your mail to @aol.com accounts, you will need to pay.
How Much Will It Cost? The accreditation application processing fee is regularly $399.00. A special charter price of $199.00 will apply to all applications submitted by July 31, 2006. The accreditation application fee is non-refundable. Please review the Accreditation Criteria before beginning your application.
I'll assume that most businesses will pay the fee to appease those clients who insist on using an @aol.com email account. I know we're in the process of applying right now. ;)
