Hi Everyone, Sorry Chris for not having an answer, but I have a similar question. we have just upgraded our server to MS SBS 2003 with exchange. My boss is getting the same problem, but it is when she sends out bulk emails.. only about 10 out of say 100 will go through. Where as before when she sent them out, they would all go through??? Pls help Justin -----Original Message----- From: Chris Chauv [mailto:chrisc@xxxxxxxxxxxxxxxxxxxxx] Sent: Tuesday, 9 November 2004 11:57 AM To: [ExchangeList] Subject: [exchangelist] getting undeliverables... http://www.MSExchange.org/ Hi all, A user is starting to get a lot of those 'undeliverable' emails from our exchange 2000 system stating that the email cannot be sent because the account does not exist, blah blah. But that user insists he's not sending emails out to anyone . so it looks like his email address is being used by spammers out there. Is there a ways to stop this user from getting those 'undeliverable' emails from getting in his inbox? thanks all -chris ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: justin@xxxxxxxxxxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
