Using an Exchange Server

[Ogma]

I have a web server running debian linux, that has php4 on it. My mail server on the network is a microsoft exchange server. I cant seem to get php to be able to send emails through my exchange server. Here is what I have in my php.ini file:

[mail function]
; For Win32 only.
SMTP = 192.168.1.5
smtp_port = 25

; For Win32 only.
;sendmail_from =

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
;sendmail_path = /usr/sbin/sendmail

How do I make this work?

Exchange might be denying your webserver to relay mail through it. Try adding your webserver's IP into the allowed list for "relaying" e-mail. I would instruct you on how to do this, but unfortunately I lost my remote desktop connection w/ my corporate Exchange server.

If memory serves, expand the "Connectors" folder, expand SMTP, go to properties of SMTP virtual server, and look around in there.

I found the relay section in Servers --> <server name> --> Protocals --> SMTP --> Default SMTP Virtual Server --> properties. I added the webserver's ip address to it. And still nothing.

Also I tried telneting from the webserver to port 25 on the exchange server and sending an email manually and it all worked out fine.
