pls define 'local citizens'. My view of "local" is surely different to

# telnet 25
telnet: Unable to connect to remote host: Connection refused


Name Server:GALLEY.USD217.ORG
Name Server:OTTO.USD217.ORG

 From Sydney, AU, the DNS records seem to have propagated:

$ nslookup.exe
Default Server:  xxxxx

Non-authoritative answer:
Server:  xxxxx
Address:      nameserver =      nameserver = internet address =       internet address =

and MX:      mail exchanger = 50

but from TX,USA:
# nslookup
 > set type=ns
Address:      nameserver =      nameserver =      nameserver =      nameserver =

and MX:      MX preference = 10, mail exchanger = internet address =

so it seems that, to begin with, you have some inconsistency in what we 
can see of your network, the answers i'm seeing from this USA-based NS 
being the old ones.

Notice that from USA, I'm getting MX pointing to otto., which it seems 
not to be taking connections on tcp/25. galley  OTOH smtp listening on

this doesnt seem at all a problem of 'MS is better than OS' or otherwise 
(wont enter in that argument anyway) - just DNS not propagated yet, and 
not much you can do about that but to wait it out, other than giving 
otto's IP to galley for the time being so  all smtp traffic goes to the 
box that is working.

Next time, you may want to reduce your  refresh settings in your zone 
before you perform a drastic change.

I'm not too sure the exact configuration you have / intend to have. do 
you want galley to forward emails to otto?
