exchange 2007 enable a relay of mail from a specific local IP

[RabbieBurns]

Im trying to setup a relay to allow a web based application on a local webserver send email through our exchange server.

Ideally I would like it to authenticate first.

It needs to be able to send as different people, so that when students reply, the replies go to the respective teacher that generated the email.

At the moment the webserver is just sending emails using its own buildin postfix, but I would like them to be going through our exchange.. Im just not sure how to go about it?

Cheers

Hi Rabbie

From my experience and best practise, I would recommend you create a new receive connector for relaying. Then I would restrict this connector with specific IP's, I.e those servers you trust to relay.

Sukh,

Thanks for the reply. Yep, thats what Ive done, created a new recieve connector and restricted it to the single server IP. But it doesnt seem to work. What do I need to set in the authentication and other tabs?

edit: when i try to connect to it via telnet, it gives the error: not allowed to relay

There are a few ways to do this. I would select Anonymous users under the permission groups and then run the command below to give the relay right

Get-ReceiveConnector "Your Receive Connector Name" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"

You could try using PHP mailer you can then use the auth against the exchange server?
