$phpMailer = New PHPMailer();
$phpMailer->SMTPKeepAlive = true;

for ( ... ) {
    // Send your emails right away
    [ ... ]


HI, I have an example code for KeepAlive SMTP here, but my problem is I send email with difference contents to my users. So each user have 1 content.

Can I do it like this:

 for ( ... ) {
       $phpMailer->addAddress($user['email'], $user['name']);
       $phpMailer->Subject = $user['subject'];
       $phpMailer->Body = $user['body'];

Will the ->addAddress increase my recipients every time on the loop? Or will it clean the old recipient after ->send() comitted ?



Call clearAddresses() Before addAddress function . It is cleared before recipients.

$phpMailer->addAddress($user['email'], $user['name']);

As it seems this is a continuing problem, let me add my own experience.

Our website uses PHPMailer and the site is hosted on a GoDaddy linux server. The settings that seemed to be correct (according to everything I could find on SO and the goDaddy support site) were as follows:

SMTP_SERVER: (or alternatively
SMTP_PORT: 465 //or 3535 or 80 or 25
SMTP_AUTH: true //always
SMTP_Secure: 'ssl' //only if using port 465

After spending 6+ hours trying every variation of ports(25, 3535, 4655), servers,[port], etc.), usernames, passwords,etc. I called goDaddy. Another 40 minutes later, it was revealed that:

1) the "workspace" email accounts are being retired. That's important because if you have an email account with goDaddy today, you likely have a Workspace account. This is, according to the tech support rep, hosted separately from you linux account.

2) goDaddy is moving toward cPanel email accounts. Hurray! Time table? " the next 2 to 3 years!"

3) I moved our accounts from Workspace to cPanel accounts while I was on the phone with the rep. Really easy to do.

4) After you change your email accounts (including editing your MX records) to a cPanel email (vs. a "workspace" email) the appropriate settings for a web-form email using PHPMailer are:

SMTP_SERVER: localhost   //(and I mean literally: "localhost"- in place of and, etc.)

... and everything else (as above) the same...

The webform I built with PHPMailer worked perfectly after this change!

Use your cPaneL email account login (username) and password in the PHPMailer setup and your web emails will work seamlessly!

An added bonus is that webmail (does anybody use this anymore?) can be accessed at [yourdoman]webmail. No more cryptic url's to remember! And the accounts cand be IMAP or POP!

Admittedly, this means you must use goDaddy's cPanel email accounts, but getting the webform to work flawslessly with PHPMailer was the real reward!

Based on you code i notice that you are sending an email directly from you web page on your domain.

For example you used an address.

When the recipient receive the emails the mail service of the recipient may test a reverse DNS of the sender of the mail. So the sender is from but the mail comes from your domain which of course is not

So I receive a mail from an address but the IP sender isn't related at all with domain that's SPAM!

I think a possible solution is: in you PHP code use authenticate with SMTP and from there send the mail!

After trying various ways, i found following code working with almost all email providers

$to['email'] = "recipients email address";      
$to['name'] = "name";   
$subject = "email subject";
$str = "<p>Hello, World</p>";
$mail = new PHPMailer;
$mail->SMTPAuth = true;
$mail->Host = 'Specify main and backup server here';
$mail->Port = 465;
$mail->Username = '';
$mail->Password = 'email account password';
$mail->SMTPSecure = 'ssl';
$mail->From = 'From Email Address';
$mail->FromName = "Any Name";
$mail->AddReplyTo('', 'any name'); 
$mail->Priority = 1;
$mail->AddCustomHeader("X-MSMail-Priority: High");
$mail->WordWrap = 50;    
$mail->Subject = $subject;
$mail->Body    = $str;
if(!$mail->Send()) {
$err = 'Message could not be sent.';
$err .= 'Mailer Error: ' . $mail->ErrorInfo;                        


variable values needs to be changed accordingly. Hope these helps people having issues with PHPmailer

Documentation says:

DISTINCT ON ( expression [, ...] ) keeps only the first row of each set of rows where the given expressions evaluate to equal. [...] Note that the "first row" of each set is unpredictable unless ORDER BY is used to ensure that the desired row appears first. [...] The DISTINCT ON expression(s) must match the leftmost ORDER BY expression(s).

Official documentation

So you'll have to add the address_id to the order by.

Alternatively, if you're looking for the full row that contains the most recent purchased product for each address_id and that result sorted by purchased_at then you're trying to solve a greatest N per group problem which can be solved by the following approaches:

The general solution that should work in most DBMSs:

SELECT t1.* FROM purchases t1
    SELECT address_id, max(purchased_at) max_purchased_at
    FROM purchases
    WHERE product_id = 1
    GROUP BY address_id
) t2
ON t1.address_id = t2.address_id AND t1.purchased_at = t2.max_purchased_at
ORDER BY t1.purchased_at DESC

A more PostgreSQL-oriented solution based on @hkf's answer:

  SELECT DISTINCT ON (address_id) *
  FROM purchases 
  WHERE product_id = 1
  ORDER BY address_id, purchased_at DESC
) t
ORDER BY purchased_at DESC

Problem clarified, extended and solved here: Selecting rows ordered by some column and distinct on another
