How to Set TTL for Exchange Server

My Exchange server is getting blacklisted for my TTL being 40000 instead of above 432000. I think I need to set this somehow in the DNS on the W2k3 server. I don't have a record for my public DNS address though. It is completely different than my local domain. Should I set up another zone for this public domain name? Where do I set the TTL for my Exchange server, and how long will that setting take to propogate to the server the company that I registered the domain name with has it set up on?

Ok, I created a new primary zone for my public domain name, increased the TTL in my DNS SOA record, and added my two public DNS servers that contain my domain name's records to the "notify of zone updates" list. I rebooted the server, and now when I ping it from inside of the network it returns TTL=255, which is good I think.

But... when I query the FQDN from the webpage that hosts the blacklist, it still tells me my MX record has a TTL of 40000!! Is this something the people I registered the domain name with are going to have to change? Also, I'm still not sure if I need this zone I created for my public domain name. Is it necissary? Thanks.

If you are using external DNS servers (which is usually the case) then it is those that need to be adjusted. Either your ISP or domain registrar will be hosting the DNS. Servers outside of your network will not be using your internal DNS servers.
If you have not set the TTL on your domain yourself then you need to ask the ISP what the reason for that is.

Which blacklist is complaining about the TTL? I haven't come across that one before and it seems a very odd value to blacklist on.

Simon.

SORBS are the one's that blacklisted me. It says my TTL is supposed to be at least 43200 and preferably 86400. Mine is set to 40000. :(
