dns help urgent

i got put on the fiveten blacklist which i have heard is not bad because of all the false possitives and not one listens to them anyway.
all my dns is hosted by at&t and all i was told to do was point all the ip's that they gave me to my server through the firewall. i was told that all i needed to to with my dns was to have a forward lookup zone that had forwarders tomy isp who host my dns.  my internal is .local and my external is .org.  the only forward lookup zone that i have is for .local??  is this my problem???  do i need a forward lookup zone with forwarders to my isp for .org??? do i need to make a forward lookup zone for .org on my internal??
i ran a dns stuffreport and i get some worns but nothing to worry about.

i wanted to know if one of the experts could tell me from their end if my smtp banner is advertising what it is supose to be advertising.  it was advertising the .local but i changed that and it is now advertising the .org like it should be.  
i have download the smtpiag tool but i am not in front of the server right now to run it.

any suggestions on my dns????

One major issue with DNS and Blacklisting is not forward lookups, but reverse.  If AT&T is providing the DNS services for your IP range, they should be able to add a reverse lookup record for your mail server.  Most times mail servers don't check to make sure that the reverse lookup resolves to the exact name in the SMTP connect, they just want to verify that there is a reverse record for that IP address.
Only if AT&T (presumably the ISP providing your IP addresses) is referring to your DNS for reverse lookup on the IP addresses they are providing would you need to have a reverse lookup for that zone.
You do not need to create a forward lookup zone or any refers, it won't affect how outside mail servers see your server.

so what do i need to do to have mail flowing out regularly??  i have changed the smtp banner and it is correct.  i have a forward lookup zone for .local that forwards everything to the isp.  so what else is there to do???
