Order of headers ->php mail()?

Hi guys and girls,

Ive read the thousands if not millions of posts on the mail() function, and **** it seems to have sooo many problems :(.

  1. I can send and recieve an email in a Hotmail account but I get the following headers:

X-AntiAbuse: This header was added to track abuse, please include it with any abuse report
X-AntiAbuse: Primary Hostname - medford.localsev.com
X-AntiAbuse: Original Domain - hotmail.com
X-AntiAbuse: Originator/Caller UID/GID - [99 99] / [47 12]
X-AntiAbuse: Sender Address Domain - in-ex.skinnyhost.com

Is this something to do with the order of my headers ??

Is the order impotant ?
