Email issues (caught as spam)

[gregjarvis]

Hey everyone, this following PHP script I'm using along with Swiftmailer is being caught as Spam on the mail server it's being sent to. The reason its being caught as spam, is because the header information is "malformed", or so my web host tells me. If anyone sees something that would cause this in the code, please let me know. Thanks.

$subject = "Website: News Story needs review/activation.";
$message = "There has been a news item submitted for review";
            
require_once "lib/Swift.php";
require_once "lib/Swift/Connection/SMTP.php";
require_once "lib/Swift/Authenticator/LOGIN.php";
            
$conn =& new Swift_Connection_SMTP("mail.midstatemutual.com");
$conn->attachAuthenticator(new Swift_Authenticator_LOGIN());
$conn->setUsername("gregj@midstatemutual.com");
$conn->setPassword("password");
$swift =& new Swift($conn);
            
$message =& new Swift_Message("$subject", "$message");
            
if ($swift->send($message, "gregj@midstatemutual.com", "gregj@midstatemutual.com")) echo "Sent"; 
else echo "Failed";

I think it's something to do with swiftmailer itself, not your code.

I can't find anything on google, so I hope someone can help you.

Make sure you have a valid From and Reply-To address and no unusual other headers, for starters. Run your script from a different host and see what you get as well.

If it is saying that the headers are malformed then look at the raw message and see if you can determine what specifically might be wrong. If you don't see anything, perhaps post them here (obscuring any sensitive information of course) and maybe someone could spot the problem.

The webhost fixed it. He didn't tell me what he specifically did, but he had to "edit" the spam filters. Wish I knew more for future cases of this problem. I'm going to assume its Swiftmailer as arkinstall said. Oh well, it works, problem solved... for now haha
