  Set oShell= Server.CreateObject("WScript.Shell")
  Call oShell.run("ping 1.1.1.1 -n 1 -w " & nMilliseconds,1,TRUE)

The trick is to create an ADO connection object and then try to connect to a non-existant server. This will block for the duration of the connection object's timeout setting.

Be aware that IIS has a default ASP Script execution time-out default of 90 seconds, so running large scripts that send volumes of email this way will time-out unless you change the asp timeout.
