Hello

after Update to 3.6.4 the mail send fails. Newsletter dispatch is ok.

@Tanja Which release did you upgrade from? It sounds like there has been a signification change in the phpmailer package which is used by phplist.

Tanja · July 29, 2021, 11:28am

3.6.3. I downgrade back to check. No problems. But since 3.6.4.

duncanc · July 29, 2021, 4:02pm

@Tanja I think that the problem might be caused by the use of a new config setting PHPMAILERSUBSCRIBEHOST. See this issue that I have raised PHPMAILERSUBSCRIBEHOST does not use smtp username and password · Issue #790 · phpList/phplist3 · GitHub

It might be best to remain on 3.6.3 until this is resolved.

“downgrade is not supported” when I use the auto-update for phplist 3.6.4.

Seems to be a similar problem as with 3.6.3

I think it should work when you put this in your config file

define('PHPMAILERSUBSCRIBEHOST','');

same error, doesn’t work for me
define(‘PHPMAILERSUBSCRIBEHOST’,’’);
phplist 3.6.4

That’s very strange. That must be something else. This line definitely says that if this constant is empty, then go to the next option

github.com

phpList/phplist3/blob/master/public_html/lists/admin/class.phplistmailer.php#L85

    
      
                  //# don't send test message using the blast server
                  if (isset($_GET['page']) && $_GET['page'] == 'send') {
                      $this->inBlast = false;
                  }
                  $this->Helo = getConfig('domain');
          
          
        if ($GLOBALS['emailsenderplugin']) {
                      $this->Mailer = 'plugin';
                  } elseif (!$this->inBlast && empty($_SESSION['adminloggedin']) && 
                      defined('PHPMAILERSUBSCRIBEHOST') && 
                      defined('PHPMAILERSUBSCRIBEPORT') && PHPMAILERSUBSCRIBEHOST != '') {
          #            logEvent('Sending email via PHPMAILERSUBSCRIBEHOST '.PHPMAILERSUBSCRIBEHOST);
                      $this->Host = PHPMAILERSUBSCRIBEHOST;
                      $this->Port = PHPMAILERSUBSCRIBEPORT;
                      $this->Mailer = 'smtp';
                  } elseif ($this->inBlast && defined('PHPMAILERBLASTHOST') && defined('PHPMAILERBLASTPORT') && PHPMAILERBLASTHOST != '') {
                      $this->Host = PHPMAILERBLASTHOST;
                      $this->Port = PHPMAILERBLASTPORT;
                      if (isset($GLOBALS['phpmailer_smtpuser']) && $GLOBALS['phpmailer_smtpuser'] != ''
                          && isset($GLOBALS['phpmailer_smtppassword']) && $GLOBALS['phpmailer_smtppassword']
                      ) {

If you want to be sure, change this line

github.com

phpList/phplist3/blob/master/public_html/lists/admin/class.phplistmailer.php#L83

    
      
                  $this->inBlast = $inBlast;
                  //## hmm, would be good to sort this out differently, but it'll work for now
                  //# don't send test message using the blast server
                  if (isset($_GET['page']) && $_GET['page'] == 'send') {
                      $this->inBlast = false;
                  }
                  $this->Helo = getConfig('domain');
          
          
        if ($GLOBALS['emailsenderplugin']) {
                      $this->Mailer = 'plugin';
                  } elseif (!$this->inBlast && empty($_SESSION['adminloggedin']) && 
                      defined('PHPMAILERSUBSCRIBEHOST') && 
                      defined('PHPMAILERSUBSCRIBEPORT') && PHPMAILERSUBSCRIBEHOST != '') {
          #            logEvent('Sending email via PHPMAILERSUBSCRIBEHOST '.PHPMAILERSUBSCRIBEHOST);
                      $this->Host = PHPMAILERSUBSCRIBEHOST;

to
