AOL presumes that any MTA whose reverse DNS indicates it is on DSL or a cable modem, is not a professional operation and a likely source of spam. They should have provided an area code 703 number to call for information. My guess is that your sendmail is the MTA of record and the reverse DNS shows something with adsl, dsl, attbi or other cable related. The solution is to take control of your reverse DNS and tie it to a domain at your site.
