This is what "the Internet" sees:
C:\>nslookup -type=any -recurse nusolutions.biz
Non-authoritative answer:
nusolutions.biz internet address = 72.151.116.178
nusolutions.biz
primary name server = ns.tzo.com
responsible mail addr = admin.tzolkin.com
serial = 2004010201
refresh = 1200 (20 mins)
retry = 300 (5 mins)
expire = 604800 (7 days)
default TTL = 3600 (1 hour)
nusolutions.biz MX preference = 0, mail exchanger = mail.nusolutions.biz
mail.nusolutions.biz internet address = 72.151.116.178
This is what happens when "the Internet" tries to connect:
C:\>telnet 72.151.116.178 25
Connecting To 72.151.116.178...Could not open connection to the host, on
port 25: Connect failed
Looks like you need to fix your DNS records (possibly your entire domain
registration), and even then, it'll take at least 24 hours for the
world's DNS servers to "catch up" (what some incorrectly refer to as
"propagation").
Here's a great online resource that you *do* want to add to your
favorites:

Subject: [isalist] NO longer able to receive email after changing static
IP...

I'm now able to send email from my internal email server, access OWA, my
websites, and RDP externally but I can't receive any email. I'm thinking
there's one item I overlooked but I can figure it out. If I attempt to
send mail to myself from the outside I get the following error a few
hours or days later:
Delivery to the following recipient failed permanently:
me@xxxxxxxxxxxxxxx
Any direction or responses are appreciated.
