ok. I did that.. but my problem i have few users who are using the SMTP server from Out of Town via regular Dialup facility from any ISP at that end... while if you look at the Relaying button that Alexander is mentioning .... it lets me put only following info....>(1) Single Computer IP Address : (2) Group of Computers and (3) Domain Now, in my case the user from our company is out of town and using dialup to use the server so I don't have (1) option ..(IP Address from his side) the other thing for (2) option he has a Laptop with him and trouble here is how can I define his laptop in Group of Computers and (3) option is ... the user who is outside uses workgroup. since he is not connected to any Network other than just dialup with ISP I don't have his domain info... Now, in my scenerio ... please tell me what should I do>???? Is there any easy way to do this??????? or even harder way would do it but inshort is there any way I can make only his Laptop use the SMTP and restrict the SMTP Relay that way???

Right click on SMTP Virtual Server and choose properties. Click access tab. Click Relaying button. Make changes as needed. --Alexander P.S. It's important to note that in a fresh Exchange 2k installation, relaying is allowed by everyone. I changed mine to "Only the list below" and require authentication. Small inconvenience that POP3 users have to authenticate to send mail, but worth the trouble. > -----Original Message----- > From: Chirag Shah [mailto:cshah@xxxxxxxxxxxx] > Sent: Friday, November 09, 2001 1:19 AM > To: [ISAserver.org Discussion List] > Subject: [isalist] Problem with SMTP Relay on ISA + Exchange Server 2K > > > http://www.ISAserver.org > > > Hi! > > I have Small Business Server 2000 with ISA, IIS and > Exchange 2K running on it.
