I am getting errors from my board when it tries to send an E-mail:

An error has occurred:

Unable to connect to the SMTP server. The following error was returned: Unknown error

The server either does not exist, or rejected the connection.

Please ensure that the UBB is allowed to relay mail through the server.

I am running Windows 2003 and Exchange 2003. I have played around with a bunch of relay settings in Exchange but can't seem to get this thing to send mail. Any Exchagne 2003 Gurus out there know what I am missing?

No Exchange 2003 Gurus out there?

i don't think exchange has something to do with sending emails it's more to manage mailboxes (though I don't have a clue really)

allen wrote an article on how to setup SMTP some time back
http://www.ubbdev.com/db/ultimatebb.php/topic/2/37.html

That is an excellent article and I have already been through it a few times. It iw written for Exchange 2000 I beleive and Exchagne 2003 is very different. I attempted to set it up as close as I could figure it out to that article. I am hoping someoone that is using Exchange 2003 can tell me what the settings are in this version.

Are there any other forums that may have some ideas for UBB/Exchange 2003 integration?

Unknown error usually indicates that there was no SMTP service listening on port 25 of the target machine.

Unfortunately, we have no documentation regarding Exchange. I'd suggest refering to the MSKB, as it may have some information on turning on normal SMTP services.

SMTP is up and running and processing mail for about 20 domains. My issue is how to allow UBB mail to pass through my server.

Can other email clients (not made by Microsoft ) talk to the same SMTP server?

Is the webserver permitted to relay on the Virtual SMTP Server. I'm still on Exchange 2000, but I had to add allowed relays for an internal server in the Virtual SMTP Server in System Manager.

I use some mailing software to send out newsletters and that works fine (non MS).

I tried opening up relay to all and it still gives me the same error.

Exchange 2003 does not have the same setup as Exchange 2000 for the virtual SMTP server, it is very confusing.

Where does UBB store the username password to use for the mail server?
