Technical Standards for E-mail Delivery
The following technical requirements apply to the delivery of Internet e-mail through AOL's e-mail network.
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.
AOL will not deliver e-mail that contains a hex-encoded Universal Resource Locator (URL). (Ex:
http://mn?/)
AOL's mail servers will reject connections from any IP address that does not have reverse DNS (a PTR record).
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 will be used as a basis for refusing connections from any mail server.
AOL may provide daily communications to postmaster@domainname and abuse@domainname (or @IP.address if no reverse-DNS or PTR records are present) to senders who may be in violation of AOL's guidelines.
America Online, Inc. ("AOL") does not authorize the use of its proprietary computers and computer network ("the AOL Network") to accept, transmit or distribute unsolicited bulk e-mail sent from the Internet to AOL members. Details on AOL's Unsolicited Bulk E-mail policy can be found at

Please Note: AOL uses member feedback to assist in the identification of the sources of Unsolicited Bulk E-mail.
