I have a user that is getting this message when she tries to email her family members. She was able to email them yesterday just fine and now today she gets this error message. All three are on different domains from each other so it isn't on their side.

I read this means the server external ip doesnt match what the smtp or whatever is expecting. I have no idea how to fix this.
 
Well does the IP your exchange is communicating out of match the IP listed in the dns records?

I cant even remember how to check...I know we didn't change anything between yesterday and today though and this issue just all of a sudden began :-(

Am I supposed to logon to our domain name registar and check the domain names ip address.???
 
your going to want to check the MX records for your domain name. That is likely controlled by your registar or web host.

Does your exchange communicate out the same IP as the rest of the machines on your network, or do you have a separate live IP setup in a 1:1 nat just for that exchange?

How do I see what IP the exchange server goes out of? I went to whatismyip.com on it and some local machines and they all show the same thing....
 
Here is the full error email I receive.

we use forefront for spam protection etc.....which is where all of our mail hits when it comes in or leaves our server......they said they had some issues earlier but that they should be resolved now. Since they aren't im wondering if the changes they made just hadn't replicated to the box we are on yet.
 
what IP is whatismyip.org reporting? does it match this: 213.199.180.150

mx:montgomerychamber.com mx

Pref Hostname IP Address TTL
10 mail.global.frontbridge.com 213.199.180.150 2 hrs
 
and you are on a blacklist:

How would I fix this issue? I put in a request with forefront due to them having a network related issue. The IP Address that whatismyip.com shows is 72.234.70.162 which is our internet pipe, we supposedly have .166 reserved for exchange but it looks like everything exchange does goes through an off site forefront server.
 
Your mx records are resolving to 216.32.180.22. Your exchange appears to other exchanges as though its sending mail from 64.20.227.133. When the receiving exchange does a reverse lookup of the domain listed in the mail header, it finds 216.32.180.22 when it expects 64.20.227.133, and there fore you get rejected and black listed. The black list problem will continue until you resolve your reverse lookup problem.

I would be talking to whom ever is in control of your outgoing mail.

Thanks for your help bud! You rock!
 
How do I check to see if out outgoing goes through them or if it is just our incoming that goes through them? (So if it is in fact outgoing and our box does that instead of theirs...I wont have to wait for tech support lol) Or would both go through since one of them does?
 
64.20.227.133 is the ip address of the network tools site......I have no idea how to fix this lol...apparently we dont use forefront for outgoing email
