Mail and hotmail

Best group member, I am sending email to a hotmail thru PHP. When I send it like this it arrives (in the junk mail, but it arrives): mail('theaddress@hotmail.com', 'A nice subject', 'Some text'); It works well, but I want to change the FROM header so I do this: mail('theaddress@hotmail.com', 'A nice subject', 'Some text', 'From: Peter Lauri <peter@lauri.se>'); This email does not arrive to the Hotmail inbox. If I send to a regular email, like Google Email (gmail) or a regular POP3 it arrives without problems. Anyone who has experienced this problem with sending emails to Hotmail? And how do you solve it? Best regards, Peter Lauri
