POP3 mail with Exchange 5.5

Yes it is possible. But not the way I would do it.

I would set up an OWA server so that they can check their mail via the web from anywhere.

Also, if you do go the pop3 route, unless you choose the leave copy of mail on server, the mail will be downloaded into their outside mailbox.

I personally have a disdain for POP3 mail in a corporate enviroment when exchange is being used.

There is a very easy way to disable your mail server to eliminate it's mail relaying capabilities.

Open up the IMS(connections/internet mail service) and go to routing/routing restrictions.
Click on advcanced and select the first check box, clients that successfully authenticate.

This will prevent mail relaying.

If you set up the OWA, do it ona seperate server, generate a fake ssl cert and apply it to the owa site, enforce ssl only no http (80). When the end user goes to the site, a warning will pop-up about the cert being bad, just press yes and they will get in.

You can have them log on to pop before they are able to relay mail. That way your spam problem will go away.

this is what i did get into the exchange admin the got to the IMS and the to the routing click routing and restrictions check the first 2 check boxes leve the box blank the will by defaulf go to the local users.. rebbot the server and you done. if you still need people to send get ahold of the ISP and ask them for there SMTP server put that in there and BAM.
