Problem recieving email to a exchange server

Hi
 I currently have an  issue with an exchange server on a SBS2003 box.

I have had to rebuild it and have run the wizard to setup internet access which works fine.

I am using a service called changeIP to control the Zone Records and have mail.domain.com pointed at the static IP address of the server.

Mail server is setup to use DNS and is sending mail out ok just not receiving it. Both MX1 and MX2 are set to changeip.com

Please help with any information that may help Im desperate

Regards

Paul h

Have you enabled your SMTP Virtual Server to allow anonymous access?  Without this - the mail cannot be received.

Is port 25 on your firewall open and forwarded to your SBS server?

Please visit www.canyouseeme.org on the server and test port 25 to see if you get a good response.

Can you telnet to your server on port 25 internally and externally?

Hi Alan

Have test port 25 and is open and can be accessed.

ChangeIP is were I can change the mx records. The @domainname.com setting is currently pointing at MX1.changeIP.com and MX2.changeIP.com and the mail.domainname.com is set to the servers static IP

MS Small business server 2003 runs a wizard to setup Internet and Email access and completed without errors.

I believe the problem is with the store and forward at changeIP but am having difficulty getting support so I need to adjust the MX records to point straight at the server and go around the store and forward and am not sure how or what to change the record to

What are IPs of mx1.changeip.com mx2.changeip.com? They should be the same as ip of mail.domain name.com

Ignore my comment. I see that it's not a problem in your case


Do you have spam firewall?

InfotechXLAuthor Commented:
No just the standard MS sbs2003 server firewall but port 25 is available from outside as I have tested it as per above and the wizard completed successfully

It's not a dns issue. That session output clearly shows that dns works, smtp works too. It's something else that is happening after email accepted by smtp listener

If I try to telnet to your server and send a test message to yourname@yourdomain.au - I get the following:

550 5.7.1 Unable to relay for yourname@yourdomain.au

This suggest that yourdomain.au is not marked as an authoritative domain name on your server and thus if that is the receiving domain, then all mail will be currently being rejected.

Please re-run the Connect To The Internet Wizard again and change the Email part to configure the Accepted domain properly.

Thanks for the points.

Great news - I'll tidy up the post to obscure any identifying details which could cause you issues.

Thanks again

I was wondering how I was going to do that and was looking for how to contact the mediator and ask how it could be done

Your a champ

You are welcome Paul - all part of the service ; )

If you ever need anything obscuring again - just look me up and drop me an email (click on my name for details).
