I am trying to get the SMTP application filter to filter domains that are spamming. My exchange server is published correctly and I have entered the domains to be filtered correctly but the filtered domains are not getting filtered! The latest isa2k.chm I downloaded (5/31/01) asks me to run setreg.vbs that's on the ISA CD. However it's not on MY CD in the \isa\i386 directory. Anyway, the online documentation at Technet says to run SMTPCred.exe. That IS on my CD. SO... While I wait to see if this works or not, I am wondering what setreg.vbs and SMTPCred.exe do? Does anybody else not have setreg.vbs on their CD? Thanks!!
