magento not sending any emails

Question

Magento is not sending any emails, no confirmation mails, no invoice mails, no shipment mails or anything. I have configured all the settings in admin also. I am working on linux based shared hosting.

Answer 1

Is there a mail server configured an running on the server? You can try and check that by making a small PHP script. Here you can see how you can do that: https://stackoverflow.com/questions/7667208/how-to-check-if-a-mail-server-exists-or-not

$errno = 0;$errstr = '';
$fp = fsockopen("localhost", 25, $errno, $errstr, 5);
if (!$fp) {
    echo "No mail server responded on this server on port 25, validate your configuration";
}

Answer 2

Check if you ve set cronjob in cpanel , if so pl check it exists , Also check if the mail address you entered is valid.

Answer 3

if you have cron issue.I solve Email Problem by disable Queue of cron . Now Sent email directly instant avoid queue. I think it is better for only low transactional magento store

/app/code/core/Mage/Core/Model/Email/Template.php 

CopyTo /app/code/local/Mage/Core/Model/Email/Template.php Line:407(approximate)

/*if (!($this->hasQueue() && $this->getQueue() instanceof Mage_Core_Model_Email_Queue)) {
    ## @var $emailQueue Mage_Core_Model_Email_Queue 
    $emailQueue = $this->getQueue();
    $emailQueue->setMessageBody($text);
    $emailQueue->setMessageParameters(array(
    'subject'           => $subject,
    'return_path_email' => $returnPathEmail,
    'is_plain'          => $this->isPlain(),
    'from_email'        => $this->getSenderEmail(),
    'from_name'         => $this->getSenderName(),
    'reply_to'          => $this->getMail()->getReplyTo(),
    'return_to'         => $this->getMail()->getReturnPath(),
    ))
    ->addRecipients($emails, $names, Mage_Core_Model_Email_Queue::EMAIL_TYPE_TO)
    ->addRecipients($this->_bccEmails, array(), Mage_Core_Model_Email_Queue::EMAIL_TYPE_BCC);
    $emailQueue->addMessageToQueue();

    return true;
