All emails going in Sending Error, but still send

Followup- if this is not the expected behavior, is there something I can comment out in the plugin code to prevent these “invalid” email from logging, so they don’t fill up the log?

Thank you!

Hi,

A mail only gets moved into the error list when wp_mail says, it couldn’t be sent (returns false).
At the moment the plugin can’t tell you why wp_mail says, the email wasn’t sent but better logging is planned for a release in the near future.

If you want to disable the storage of mail errors you can change the following code

foreach($mails as $file => $data) {
    if($this->sendMail($data))
        $this->deleteFile($file);
    else
        rename($file, self::getUploadDir(true) . substr($file, strrpos($file, "/") + 1));
}

in classes/SMTPMailingQueue.php in lines 324 – 329 to

foreach($mails as $file => $data) {
    $this->sendMail($data)
}

Please note that this will be overridden when the plugin gets updated. Also, you won’t see any sending errors anymore.
