I need to send the same email in plain text format to several users.
I can do that, but there is a problem: those users who use a gmail account (and only them) can see the email addresses in the Bcc field.

Is there a way to hide those addresses to gmail users?

This is my code

$i=0;

while($row = mysql_fetch_array($addresses)) {

    if($i==0) //first addres into the field To:

        $receiver = $row['email'];

    else //others into Bcc

        $bcc .= $row['email'].", ";

    $i++;

}


$header .= "MIME-Version: 1.0\r\n";

$header .= "Content-type: text; charset=iso-8859-1\r\n";

$header .= "From: My site <email@mysite.com> \r\n";

$header .= "Bcc: ".$bcc."\r\n";

$object = "email's object";

$message = "email's text.\r\n";

mail($receiver, $object, $message, $header);

I'd skip mass mailing in one message, and send each user a message instead, directly addressed.

That's a solution, I know, but I'm on a shared webserver and if I generate a too heavy load, my site will be suspended, so I'm trying to optimize the resources.

Any user can see the BCC when viewing headers - I think some if not more will let you download the entire message revealing the BCC I think.

I would just go with the sending to multiple users - I think most shared servers just notice you if you do a lot at once - put a pause or something in there - or possibly do the first 100 this hour and the next the next hour - or do it alpha or something?

I do not think there is a way around people seeing the BCC...

EDIT:
You could use some method to get the domain of the email - if you dont have many gmail users you could just make a special case for them then add the other ones up and BCC them...?

This is an intersting solution.

Its performance is based on how many users you have and how many Gmail users you have but if you do not have many compared to the amount of users you should be okay. Not everything has a function for it I suppose sometimes you just have to improvise ^_^
