- AOL's servers will not accept connections from unsecured systems. These include open relays, open proxies, open routers, or any other system that has been determined to be available for unauthorized use.
- AOL's mail servers will not accept connections from systems that use dynamically assigned or residential IP addresses.
- Organizations may not hard code AOL's MX records into their configuration files.
- All e-mail must be RFC compliant.
- AOL's mail servers will reject connections from any IP address that does not have reverse DNS (a PTR record). All e-mail servers connecting to AOL's mail servers must have valid and meaningful (not dynamic-looking) reverse DNS records.
- AOL may reject connections from servers whose recipient lists consistently generate a higher than 10% bounce failure rate. (i.e. over 10% of a sender's mailing list is destined for users that do not exist on our system)
- AOL may reject connections from senders who are unable to accept at least 90% of the bounce-return messages (mailer-daemon failure/error messages) destined for their systems.
- Complaints submitted by AOL members may be used as a basis for refusing connections from any mail server.
- Persons sending bulk mail from the whitelisted IP Address must immediately remove any e-mail address which causes a permanent failure "bounce" message to be generated with one of the following error codes:
- 550 "AOL username" Is Not Accepting Mail From This Sender
- 550 Mailbox not found
- AOL, LLC does not authorize the use of its proprietary computers and computer network to accept, transmit or distribute unsolicited bulk e-mail. AOL's unsolicited bulk e-mail policy can be found at http://www.aol.com/info/bulkemail.adp
Please Note: AOL uses member feedback to assist in the identification of the sources of unsolicited bulk e-mail.
