Mike, Sounds like a user pswd has been hacked. I just went through a similar situation. I recommended a complete pswd change for all users and better security standards for the users. Are the msgs coming from "bluestell" as the sender? Ken -----Original Message----- From: Mike Pfeiffer [mailto:mike@xxxxxxxxxxx] Sent: Wednesday, October 08, 2003 3:28 PM http://www.MSExchange.org/ I just came across an Exchange 2000 server at a customer site that has hundreds of messages in the outbound queue. The server is not currently an open relay (tested using the telnet method) but all of the messages are from addresses from outside domains to users in outside domains. Why would these messages get put in remote delivery queue if the server doesn't allow unknown users to relay mail? Thanks for any help
