I had set 'email interface:Lotus Notes'.
My script is :

MailSend( "wzy", "wzy1998", "joe", "Test","OK! OK!" )

Ver:2.4.7

Which error do you get, which Notes version do you run?
Is "wzy" youy Notes Id or just email name?
If "joe" correct recipient name? How about "joe@[yourdomain].com"?

Do you have Notes home directory in the system path?
After you selected Notes interface in the 24x7 Options, was the installation of Notes interface successful and if yes, have you restarted Notes after that?

Do you run 24x7 from a local drive on your computer or from a shared network drive?
