MOSS 2007 Outgoing Email

I'm running MOSS 2007 on a Windows Server 2008 R2 Server....  I can email documents to my document libraries with no problem, however outgoing email is not working.... I'm using smtp from the moss server, not my exchange server... so the email should be coming from spadmin@sharepoint.domain.local, as opposed to my corporate exchange server...  when setting permissions in moss, I check the box to send email to the new member and get the following error....

"The user or users have been added successfully, but there was an error in sending the e-mail message. The server may not be set up correctly to send e-mail. To verify that e-mail is configured correctly, contact your server administrator"...

I know it's got to be a smpt permissions issue, but just not sure where in 2008 to fix this...

are sharepoint alerts working or not?
i think your probelm is a firewall or macafe problem
if you have an anti virus like macafe then uninstall it and try to send the email again

I'm not running any sort of email program on this server, do I need to be in order to be able to send mail?  I telnet to the server and  enter mail from: spadmin@sharepoint.domain.local, and get 501 5.5.4 Invalid address... do I need to add this address somewhere??
For outgoing email. you dont need to add a valid email but i think you should add .com in the end of the email

I believe you are using normal IIS smtp services, you need to confirm following;
1. SMTP services are running.
2. Server IPs are allowed as relayed.
3. Anomyous or proper security configured.
4. Domain name added which you are using for sending email from MOSS.
