I recommend you use Zend_Mail instead of mail(). It handles a lot of stuff automatically and just works great.
First of all I would switch to using Zend_Mail. Second I would use a real mail account on an smtp server somewhere and send from that. A lot of times there are restrictions on sending from the server itself, but using an actual mail server usually fixes this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
