mail() function not working with sender's hotmail email

[crescent_au]

hi all,
i have this mail() function which works fine but i've tested it with
hotmail where i use hotmail email address for sender and receiver also
hotmail. If I type in a not existent email address for sender and a
right address for receiver, the email is not sent. But if I use
non-existent email and yahoo receiver email, then the mail is delivered
correctly. What's with hotmail? Is there something I can do to prevent
it with mail() function, or extra headers? or is it simply something to
do at the hotmail's end?

Thanks
Ben

because its going to a hotmail address their filters can see if the
senders address is valid or not. Yahoo! doesn't have access to hotmail
accounts so they can't verify. Guess you will have to use yahoo! for
your spam script.
