Thank you Michael, its working great, Now that its working I want to ask about ppl who mistype an address they don't get an NDR, is this ok? I think this is much better for the exchange but am not sure if its a common practice and ok to do tx -----Original Message----- From: Michael B.

In "catchall.cmd" are the lines: cscript //nologo smtpreg.vbs /add 1 onarrival SMTPScriptingCatchAll CDO.SS_SMTPOnArrivalSink "mail from=*" cscript //nologo smtpreg.vbs /setprop 1 onarrival SMTPScriptingCatchAll Sink ScriptName c:\ExchangeScripts\CatchEmail.vbs cscript //nologo smtpreg.vbs /delprop 1 onarrival SMTPScriptingCatchAll Source Rule You change the "1" here to be the ID of your SMTP virtual server. (You can use enum.cmd to find out which is which.) Thanks, Michael
