For assistance, contact your system administrator. #5.7.1 smtp;550 5.7.1 Unable to relay for postmaster@xxxxxxxxxxxxxxxxxxxxxx>" Did you change anything on the VS? Is anonymous access disabled? Authentication changed? Did you run the SCW that comes with SP1 and lock something down? Recipient policies ok? ________________________________ From: Andrew English [mailto:andrew@xxxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, April 13, 2005 7:27 PM To: [ExchangeList] Subject: [exchangelist] Exchange Problem http://www.MSExchange.org/ It seems that I am having a problem with my exchange server since I install SP1 for Windows 2003 Server. I am running Exchange Enterprise 2003 and use one storage system for 3 domains, the main one smoothrunnings.ca and the other two which are UPN addresses. The issue is that I can receive emails on my other 2 domain UPN addresses without any problem, its my smoothrunnings.ca (primary) that is no longer working. When I send email to my SR accounts from an external source the bounce, however if I telnet to mail.smoothrunnings.ca I get my exchange box. Also I am not getting any errors in the logs, I also see the email leaving my machine via Trend's ScanMail monitor but it doesn't go anywhere. (shrug) Any ideas? Thanks Andrew
