Hi John, Exactly, but how we setup in mail client - Microsoft Outlook 2000/XP. I could not find any configure option for that. Of course you can set on Outlook Express! By the way I assume E2K support SMTP AUTH, so is there any possibility setup from server side rather than setting up from client side while allowing only to legitimate users & restrict to spammers! - Hirantha -----Original Message----- From: John Tolmachoff (Lists) [mailto:johnlist@xxxxxxxxxxxxxxxxxxx] Sent: Thursday, August 21, 2003 9:08 PM To: [ExchangeList] Subject: [exchangelist] RE: Exchange for Roaming users http://www.MSExchange.org/ Yes. It is called SMTP Authentication. It is a setting on the e-mail client.

Is there a possibility to configure SMTPVS or SMTPC on e2k server without being open relay! While allowing legitimate users to send e-mails from any place (IP) in the world and preventing spammers and unauthorized people from using you Exchange server.
