Interactive Net Server v7.0.454.5 Lines: 80 Hector: I like the greylisting idea. I never thought about the temporary rejection - try again thing. Over the past couple of years I have put off doing the wcsap install mainly because I have been covered up with company details. However, I plan to take a look at the greylisting thing next week. One question; do I need to install wcsap first? Or, is this a simple change in the DATA\WCSMTP.INI attempt timing?
