vbscript not running in php but running as a vbs file

hi im having a problem with a vbscript that sends mail . Set objMessage = CreateObject("CDO.Message") objMessage.Subject = "mysubject" objMessage.From = "mymail" objMessage.To = "destinator" objMessage.TextBody = "mytextbody" objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mysmtp" objMessage.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25 objMessage.Configuration.Fields.Update objMessage.Send if i run this like a vbs file it runs like a charm . i receive the mail no problem . if i add this to a php page with the tags <SCRIPT LANGUAGE="VBScript"> ...... </SCRIPT> it does not work . it does not give any error .....and if i check smtp server log it does not even get to the server . it looks either it does not process or it doesnt leave the workstation. any ideias ? thks in advance rgds rui
