making php mail code work for hotmail

[stubarny]

Hi Eveyone,

This code was working for hotmail, googlemail and SquirrelMail but sometime in the last few weeks the code has stopped working for hotmail.

The mail doesn't even arrive (i've checked junk folders) and I don't get a delivery failure email to my host account's email address.

Do you know what may be wrong with it?

Thanks!

Stu
