AOL on Thursday apparently began bouncing emails containing the "Dearaol.com" URL - which is for a petition against AOL's controversial certified-email program - according to nonprofit MoveOn.org (as well as the Electronic Frontier Foundation), CNET reports. Dearaol.com contains an open letter and a petition that calls on people to protest what it calls an "email tax" being imposed by AOL.

AOL spokesman Nicholas Graham said late Thursday that AOL emails containing "Dearaol.com" would be delivered as normal. He said a software glitch had "affected dozens of web links in messages," including Dearaol.com.

That site was set up by a coalition against AOL's adoption of GoodMail's CertifiedEmail, which allows requires marketers to pay in order to circumvent spam filters and ensure delivery of their email messages.
