I've a site with logged users. These users have an associated email
adresses stored when they create their account. They can send email
between themselves using a dedicated form with email() PHP function
inside.
As I want that the user can do a reply that will work. I try to put
the sender email in the header.
It seems that this process works in 75% cases but sometimes the email
is not delivered to its sender. I begin to assume that some providers
think that my email is a SPAM or junk mail and trash it before
anything.
Here is my email header :
To: de*********@otherworld.com
Subject: blablabla
From: se****@world.com
Reply-To: se****@world.com
MIME-Version: 1.0
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 8bit
X-Sender: <se****@world.com>
X-Priority: 3
X-MSMail-Priority: High
Thanks for any help/informations
