Please take a look in the Exchange queues.
Also try the "telnet test" from your Exchange server:
http://support.microsoft.com/kb/153119
and let us know the results.
did you get "4.7.1 Client host rejected: cannot find your hostname"?

I can't connect to their server via Telnet! Possibly a config issue with their server.
What is your domain name and IP address - I will check that you are configured properly (and I will obscure / hide / delete the domain name and IP address once you post it).

Alan,
IP for exchange? And not sure if I am comfortable giving that info out? Isnt that a security concern? I am not familiar with Telnet.

If you don't want to post the info (which I appreciate), you can email me at alan @ it-eye.co.uk.
I am a Zone Advisor and can hide / delete / modify your comments, so the info mwould not be made publicly available once I have obscured it.

jsut use the commands from my earlier post
I have tried telnet and it fails.
ASKER
I tried the telnet too it failed. nslookup worked fine
please post the failure code
I think the issue is on their end

Telnet mx.grupoconecta.com.br 25 error:
450 4.7.1 Client host rejected: cannot find your hostname, [216.120.xxx.xxx]
Telnet mx.grupoconecta.com.br error:

they are blocking you
make sure you are not on any block lists

OK so because we cant telnet to them we are blocked somehow on there end. As I am not familiar with telnet other than what I just googled and experienced here, I am curious to understand how telneting determines that. Can you explain briefly and I shall close this question. Thanks Everyone for all your help.

when you telnet via port 25 to the other email server, you can see the response from the other email server; if the response is an error, such as "Client host rejected: cannot find your hostname" you can act accordingly; this would be the error your exchange server is getting from the remote email server
@alan - you have the advantage here of knowing additional info :)
The info was posted for all to see.

Alan,
DNS is my week spot as I havent worked with it since my formal training 3 years ago. I can not find on our domain controller in DNS the MX record or reverse DNS you mention. Can you advise.

Reverse DNS is setup via your ISP - you need to call them and ask them to change it for you.
ASKER
Ah I see. I found the MX record the priority is set to 10 not 0 ?
Yep - 10 is fine - anything other than 0 works ; )
Have you run the Exchange Shell command I posted?
ASKER
not yet also, you said priority was set to 0 in a previous post and it was not. Just wondering if this changes your recommendations based on it was already where it should be.....
The MX priority will affect inbound - it won't affect outbound. I am just being tidy : )
Extract from www.dnsstuff.com for your domain (assuming I have the domain name correct):
Your 1 MX record is:
0 mail.your-domain.com. [TTL=3600] IP=216.120.xxx.xxx [TTL=3600] [US]
Your 1 MX record is:
0 mail.your-domain.com. [TTL=3600] IP=216.120.xxx.xxx [TTL=3600] [US]

Alan,
I turned on the recipient validation. Sound like this will block a lot of spam before its even filtered by our Ninja Spam filter? Seems like the Spam filter should be doing that before it hits Exchange? I am waiting for my ISP to get back to me on the reverse DNS we have discussed it. The mentioned flowrite01 is a long ago decomissioned server?

I just sent a test message to "contato@grupoconecta.com.
This suggests that the problem is definitely at your end.

Also, We use godaddy. I see our MX is 0 on godaddy but 10 on our DC. I am thouroughly confused now.
Yes - the changes should make your situation much better.
Your MX records should only be on GoDaddy - there should not be an internal MX records as you should be relying on DNS externally to resolve things.
