Original Post (August 2000) A web-based e-mail service which was bought out by Yahoo! and is now a part of Yahoo! Mail.
Yahoo! has very little, if any at all, support for rocketmail users. Often, when one tries to use their rocketmail address when filling out an on-line form, their address is seen as an invalid one. They are then unable to set up an account. ...Yeat another reason why Yahoo! Mail is terrible! Update (September 2003)

I still have my rocketmail account through Yahoo! Mail. It is actually my primary e-mail address now. I no longer have any problems with Yahoo! and am quite pleased with the service. Their spam filters work especially well compared to Hotmail.
