Hi,

I just want to share something I figured out. I am using XOOPS 2.2.3a for a corporate intranet on my WinXP Pro PC. I wanted to use the corporate Exchange server to send email. Here is what I learned:

1. You don't need to run the Windows SMTP service to do this. The phpMailer included with XOOPS will talk directly to Exchange.

2. The phpMailer version included in XOOPS 2.2.3a is a little old and does not support EHLO which was required by my Exchange server. I simply downloaded the most recent version 1.73 from sourceforge.net and updated these two files:
class.phpmailer.php
class.smtp.php

3. You need to configure XOOPS in the Preferences | System | Mail Setup screen like so:
Delivery: SMTPAuth
Path: doesn't matter
hosts(s): hostname of Exchange server(s)
username: your windows account name (I didn't have to prefix my Windows Domain name)
password: your windows password
From Address: your Exchange email address

I also found this site useful:
exchange2003_SMTP_Auth_Login

Hope this helps!
