which one is right? the mailer daemon thing? if you want this, then I think all
you need to do is set the [b]failto [/b] parameter of your cfmail tag with the
email you want the failure notification to be sent to.

but if you want your cf  app to give you the true or false value, then maybe
you should have a mailsent log file mentioned by Dan and make some checkings on
that file. you can enable this log in the cf admin under Mail in the server
settings. Once enabled, if you're using cf8, the log is usually created/updated
in C:\ColdFusion8\logs\mailsent.txt every cfmail. There, you can let cf(maybe
try doing some cffile) read and parse the file and do some checkings in order
for your cf app to determine if the mail has been succesfully sent or not.
