Signing mails sent through SMTP with DKIM?

Yes, it's actually a server configuration thing. But since you posted on SO, there is also a way to sign the mails manually from within PHP. http://php-dkim.sourceforge.net.

I create new project in googlecode. The name was phpMailDomainSigner It support DKIM-Signature and DomainKey-Signature in Object Oriented Style.

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.
