Configuring Exchange 2007 for internal SMTP

[Edu-IT]

At present we route all our outgoing email through a smarthost - so our Exchange box is just acting as a relay at the moment. What I want to do is get the box to handle SMTP for certain internal systems and process the mail itself without going through the smarthost and back again.

 

Is this achievable? Any advice on how to do it?

Don't know because I'm confused... where are 'certain internal systems' sending the mail? Is it to a mail address associated with a mailbox on your local Exchange?

[glennda]

If the mailbox resides on the local server (i.e you are sending an email from a local server to yourself). The server will deliver the email directly to the mailbox. It will only try and route the email externally if it does not recognize the email address (i.e you try to send to a hotmail address)

Might be easier just to install the IIS smtp service on a random computer.

 

Thats what I did and it only took 10mins.

 

Now all our sharepoint, photocopiers and internal systems can send mail very easily with no security implications.

That's a good idea!

You could also setup a separate relay address on the exchange box - remove all authentication and only allow certain addresses to send mail to it.

So would that be a seperate receive connector that doesn't forward mail on to the external mail scanning engine?

yarp yarp - for us it just removes the awkward authentication layer for legacy stuff - but should work for your needs too.

So with that in mind:"Each connector has a unique set of the following attributes: IP Address, Port number and remote IP Address range"What would be the best way to configure the additional connector without screwing up the existing one? How do you achieve it?

[sukh]

Simplest thing is to setup a receive connector and add in the IP's to allow relaying. The main question you need to ask yourself is do you want them allow relaying internally only or externally too.
