I have found that if I send an email from my server using a SetFrom email with the same domain as the recipient's AddAddress, it will get bounced by some recipient's email server as a spam prevention measure. As a workaround, I planned on using a different SetFrom email whenever the SetFrom had the same domain as the the AddAddress. It works when sending one email with a given phpmailer object, but not multiple.
<?php
function getEmail($from,$to,$default='auto@mydomain.com')
{
$from_parts=explode('@',$from);
$to_parts=explode('@',$to);
return($from_parts[1]==$to_parts[1]?$default:$from);
}
$user_email='john.doe@bigcompany.com';
$user_name='John Doe';
$mail = new myPHPMailer(); //Using phpmailer 5.2.9
$mail->AddReplyTo($user_email,$user_name);
$mail->Subject = 'The Subject';
foreach($people AS $person)
{
//If sending email to same domain, use a different email so it doesn't get bounced by some email servers.
$mail->SetFrom(getEmail($user_email,$person['email']),$user_name);
$mail->MsgHTML('Custom message created for each person');
$mail->ClearAddresses();
$mail->AddAddress($person['email'], $person['name']);
$mail->full_name=$person['name'];
$mail->Send();
}
?>
If $people just contains one person who's email has the same domain as the sender's, it successfully goes through. I don't think I need to provide the header information, but did so below for reference purposes only.
