I read the script file, seems to me the "iInstance" is the SMTP ID variable? however from what I could understand its not called in the smtpreg.vbs, its called in the catchall file: "cscript //nologo smtpreg.vbs /add 1 onarrival " ? Please can you tell me if you don't mind is it this one I should change? or is it Binding.ID. many tx -----Original Message----- From: Michael B.

I can't enable the default one......I think its infected :D this sounds crazy I know, but when I enable it (it has the same settings as the new SMTP) the queue starts filling up and email takes days in the queue before it leaves, if I delete the bad mail folder, and everything in the queue , the minute I start it again it has all these messages already in there (which I deleted before) and the queue starts growing again :) tx
