It is fine and tells us that name resolution through Sendmail works properly on your host. Take the Paul's advice and place the ISP's smart host name into squared brackets: [smtp.aol.com]. This prevents Sendmail from trying to find the MX through DNS. You then should no longer get an error "stat=Deferred: Name server: smtp.aol.com: host name lookup failure". The "stat=Data format error" you get when authentication against the ISP's smart host fails. You can probe authentication manually by running the (E)SMTP manually using telnet to port 25. google.com holds several examples on how to do that.
