first of all have you run through all the Wizards in the SBS Console?  This configures Exchange for your domain name.

secondly, forward port 25 on your router/firewall to the internal IP address of your SBS server.

thirdly, you need to configure your external DNS.

In the control panel for your external domain name configure an A record.  As this is SBS I would suggest that A record is remote.domainname.com (replace domainname.com with your actual domain name), this should point to your private IP address which you can find by going to http://whatsmyip.org

Once that's done, configure your MX record to use the A record you just created.  This will allow mailflow to your mail server.

And then finally for consistency and to prevent your sending mail from being rejected, ask your ISP (the provider of your data connection) to setup a rDNS or PTR record for your IP address of remote.domanname.com (again, replace domainname.com with your actual domain name)

see my guide here on DNS configuration: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2370-Exchange-DNS-Configuration.html

Hi there!

You've indeed established a MX record; but somehow no connection to the referred IP is possible over port 25.

Can you make sure that :
- you forwarded TCP Port 25 to that server (or from to a mail filter)
- the MX-record is correct?

Thank you!

Can you confirm what you are running? The question title says Exchange 2007 and the question itself says windows 2003 SBS...

DNS changes wil take 24-48hours to take effect. Check your MX/DNS config from www.mxtoolbox.com and see if that website can talk to your server (open relay test)

OK, first of all, your MX record is using an IP address, this is non-compliant, you should only use an A record (it's all detailed in my article)

There seems to be numerous DNS issues, this is probably your registrar causing this problem but it shouldnt effect your email.

Fix the MX record.

OK, first thing you need to create an A record, as it's SBS call the A record remote.yourdomainname.com (replace domainname with your actual domain name)

Then confivied your MX record to use that record (delete the others).

This is all detailed in my article I posted in my first post.

Then, make sure port 25 is being forwarded from your router/firewall to your SBS servers internal IP address, currently port 25 is not open or if it is it's not being forwarded to the correct place.

If you have port 25 open and forwarded tithe correct place then is likely your ISP is blocking port 25.  Goto http://canyouseeme.org and check

Yes, you must use the wizards, this will ensure that all proper settings are configured, SBS is designed to be managed with the wizards.

I have just done a telnet test on your mail server and it would appear that @innlinktechnologies.com is not an accepted domain, have you completed the Setup Your Internet Address Wizard in the SBS console?

You can bit it goes against best and recommended practice.

I've never seen the wizards complete and not do what they are supposed to.  The fact the question came up regarding the ports above indicates the wizard hasn't been completed previously.

Most if not all configuration problems with SBS are caused by manual intervention and/or not running the wizards.

@vikrantambhore - what SP level of Exchange 2007 are you running? It might be time to install SP3 if you haven't already done so.

The error is saying the wizard cannot open the ports so you will need to do it yourself.

Make sure at a minimum ports 25 & 443 are forwarded from your firewall/router to the internal IP address of your server.

Goto: http://canyouseeme.org and check if port 25 is open.

You DO NOT want people relaying off your server.

Can you run:

Get-ReceiveConnector | fl

Post tge results.

Also prt 25 is definitely being forwarded to your SBS servers internal IP?

Can you check the queue viewer? Are there any queues with messages in??

Do you have any SPAM or Antivirus Software installed on the server? If so remove it and reboot.

Have you by any chance disabled IPv6? If so re-enable it, and reboot.

Are there any services that start with Microsoft Exchange set to automatic that are not started? If so which  ones?

Silly question  of the day....you have created some users that have email addresses!?

Have you tried running the Fix My Network Wizard? Under Networking and Connectivity in the SBS Console? If so what does it bring back?

If you send a test message, what happens? Do you get a bounce back?
