i just realise mails from my mail server is getting bounced, with mails to AOL especially. I think its because I didn't specify reverse dns on my mail domain... but I have never done reverse DNS before...
do I need to create a new zone file... or do I just add the PTR records into the existing domain zone file?
Who do I need to inform (ISP or anything) and what do I need to note? as I have read of cases of people who's email server didn't work after specifying the PTR

thanks!
Normally whoever is providing the IP can handle this for you, and prefers to do so. Since they own the IP, they CAN delegate PTRs for blocks, but they normally feel it's not worth it for a single IP (or even 2 oe 3 IPs). Ask them. I'm sure they'll fix you up, and I have never had one charge me for it yet. Then you just handle the "normal" DNS records yourself.
AOL doesn't care WHAT the PTR says, as long as it's there. They don't even have to remotely match for AOL to be happy.
