Hi Andrew, Add the printers IP address as one of the exceptions in the SMTP Relay configuration menu, that way the mail server will not require SMTP authentication on send. Jose -----Original Message----- From: Andrew English [mailto:andrew@xxxxxxxxxxxxxxxxxxxxxx] Sent: Thursday, June 09, 2005 5:44 PM To: [ExchangeList] Subject: [exchangelist] Exchange relay http://www.MSExchange.org/ I am running Exchange 2003 Server which is IP 192.168.0.3, I have a Xerox WorkCentre Pro 55 copier which also does email on the same network; IP address 192.168.0.114 I am having an issue with SMTP internally. When I send out a email via the Xerox it never goes out unless I setup the Xerox to authenticate with the SMTP server and add the user associated to the Xerox machine (info@xxxxxxxxxxx) to the Exchange Relay as a able user to relay. Is this the correct method or is there a better way to do it?
