Email not going out in Exchange 2007
I have a client with a SBS 2008 exchange box at his jobsite and moved it to his ATT modem equipped home. I have setup a Netgear router behind the ATT modem (which is in pass-through) and have equipped the ports all from the other setup for mail, gre, rdp, etc,, I have the new outside IP embedded in the Netgear along with DNS, Gateway subnet, etc. The internal IP of the server is the same.
The internet, printers, and dns are working, but can't get mail to go out from Exchange 2007. I have run BPA on exchange, message tracking, and any other tools to see why it just sits in the queue including Fix my network. My submission queue shows 0 files, but the messages tab has 8 and increases when I try to add more to send out. The queues are not suspended, local emails are listed as well as outside mails
Driving me batty, spending way to much time on this.

I have an existing send connector, yes. I have not recreated one. I will call ATT to see if they are blocking 25.
In the powershell Check the port
Get-SendConnector | ft Id*,Sm*s,po*
if it's 25 then run this and change to another port such as 26
Set-SendConnector “OutboundMail” -port 26
restart the transport service and send mail
Get-SendConnector | ft Id*,Sm*s,po*
if it's 25 then run this and change to another port such as 26
Set-SendConnector “OutboundMail” -port 26
restart the transport service and send mail
pcdev,
that may work but port 26 is usually used for encrypted smtp, the receiving mail servers will probably reject it anyway.

Very true, Joshua, thanks for reminding me.
Other ports to try are 487 or 587

pcdev, what is "OutboundMail" name?

Im being told that ATT will not open port 25,, If I change the server port to another, what other things do I have to change?
You shouldn't need to do anything other than tell you send connector to use another port other than 25.
Have you tried setting it yet? give it a try it won't hurt

One thing you do have to worry about is if ATT is also blocking port 25 for incoming.
Have you verified that you can receive mail?

I have changed it to 26 and 587 and it will not go.. Will try 2525 and see
i think you do have to restart the transport services. if still no send then a full reboot
Any news on this yet?
ASKER
I tried 8 different ports, and it still says error 421 4.2.1 Unable to connect.. I think I will just move them to Office 365,, ATT will not open the port 25, but they are not alone either, lots of ISP providers won't

Joshua was the one to point out that Home based ISP's block port 25, so I give him the points.. Thanks to all, The client was moved to cloud exchange.
