E-mail from PHP goes to junk mail in hotmail

[pibolito]

I have this problem for some time and I never solved it :\
I tried 1 millions ways and everytime e-mails sent from a PHP script go to junk mail in hotmail.
Did anybody find out the trick already? If so I would appreciate very much if he/she could share with me.
Thank you already for the help

I would suggest looking at the header properties.

You may need to specify more information about the mail you are sending, because of the filters that Hotmail uses.
