Small Business Server SMTP connector not delivering mail.

I am having an issue with the Exchange SMTP connector for rogerswirelessdata.com not delivering mail to a client's windows pc phone.The messages are stuck in the server queue and a restart of the SMTP service and the entire server have not resolved the problem. I have verified with Rogers Wireless that I am using the correct information for their server. The perplexing part is that during the initial setup and test, messages were routed correctly and delivered. The failure began to occur about 36 hours after the initial setup was complete. Any ideas on what is causing this issue?

Can you telnet to port 25 of their mail server from the Exchange server?

Although the domain rogerswirelessdata.com doesn't appear to have any MX records, so if you are trying to route by DNS then it will probably fail.

Thank you. You have pointed me in the right direction. I have spoken to Rogers again and pointed out to them that rogerswirelessdata.com does not have any MX records. I was then provided with: pcs.rogers.com which does have MX records. My question now is; can I correct the address on the server, or do I need to do this on the device itself? If I can do it on the server, what are the steps involved?

The fact that you are forwarding email to phones does not matter, as far as Exchange is concerned you are just sending an email to an address.

Have the phone company told you to use a different email address or domain? If so I presume that you are putting email addresses in somewhere for the forwarding to take place. If you are, then you need to update those email addresses as appropriate.

The problem is that on the phone, when you setup automatic notifications (push technology stuff) you enter in an email address, which corresponds to sending text messages to the phone. Thus, when a new email is recieved, Exchange sends a text message to the phone telling the phone "hey, check your email," which starts the activesync process.

The question before the court is: can we change that notification email address without having to have the phone in hand (it is 2,000 miles away) and re-running the activesync setup wizard on the phone (Windows Mobile 6) or can I set that email address in active directory / exchange manager somewhere?

Push doesn't use the text message method any more if you are using Exchange 2003 SP2. It uses http packets. I didn't even think WM6 supported the old text message method.

I think you may have setup the push technology in the wrong way.

This is my guide to setting up push.

I would suggest that you get hold of the Windows Mobile emulator from Microsoft and try it for yourself.

Me thinks they don't have direct push. It's old school text message notification.

Here are two reasons why:

The first is the MObile Services Properties screenshot, and the second is an SMTP connector queue that has 21 messages in it because the recieving server needs to be changed (what sparked this whole thread).

That means the server doesn't have Exchange 2003 SP2 installed. I wonder what else it doesn't have. Check whether the server is up to date at all - Windows 2003 SP2, SBS SP1, Exchange 2003 SP2 plus updates that are released after that.
