I tried to send notification mail in PHP to my group email, but these updates, doesn't appear. the code is like this:
$to = "firstname.lastname@example.org";
$subject = "test mail";
$message = "Hello! This is a simple email message.";
$from = "email@example.com";
$headers = "From:" . $from;
echo "Mail Sent.";
FYI, firstname.lastname@example.org contained a few members. i got this trouble since it was distributed mail group. but if the recipient is an individual mail, its working properly. did php not support distributed group mail?
