How do you use Helpdesk e-mail without enabling POP3 on the Exchange server?

Q:
Ethan asked, "Is there a way to use Helpdesk e-mail without enabling POP3 on the Exchange server? SMTP is the only protocol in use."

A:

Ethan, one possible workaround is to set up a mail server on the Altiris server. You can use the built in MS POP service and IIS SMPT server to do this.

1. First you setup the SMTP service and create a receive domain there. Typically the DNS name of the server. Then you are able to receive e-mail from the Exchange server.
2. Then you setup a MS POP service. In Properties on your server, you can set the root mail directory to the SMTP directory. Create the same domain as in IIS SMPT and under that create a helpdesk@yourserver.corp.com mailbox to pop. You can test this using Outlook Express.
3. When you have the mailbox working (when you can send e-mails to it using Outlook Express and the Helpdesk is picking it up) have Exchange forward all helpdesk@corp.com e-mails to helpdesk@yourserver.corp.com
