Invalid email address triggers 500 error on Joomla 5 + VirtueMart 4.6

[holanpan7]

Hello,

I've encountered an issue with VirtueMart 4.6.0 (build 11214) running on Joomla 5.

When a new customer account is created with an invalid email address, VirtueMart tries to send the registration email.
Since the domain does not exist, PHPMailer returns an SMTP error :
SMTP Error: The following recipients failed: xxx.xx.vom: Requested action not taken: mailbox unavailable invalid DNS MX or A/AAAA resource record 1MT9v5-1vdEna0eaN-00XCDc

The result is a full 500 crash, even though the user account is actually created correctly.

In previous VirtueMart versions, an invalid email would simply display a notice such as SMTP error email invalid not a fatal error and the registration process continued normally.

Is this a known issue with VirtueMart 4.6 on Joomla 5? Is there a workaround?

Thank you for your help!

Hello,
I'm still experiencing this issue in VirtueMart 4.6 on Joomla 5.
Could anyone confirm if this SMTP crash on invalid email is reproducible on your setups?

Thank you in advance!

Hi,

I think (hope) i managed to solve the problem.

in administrator\components\com_virtuemart\models\user.php

I changed

Code Select Expand

// Send the registration email. if (VmConfig::showDebug() and $debug_email == 'debug_email') { $msg = 'Registration Debug mail active, no mail sent. The mail to send subject ' . $emailSubject . ' to "' . $data['email'] . '" from ' . $data['mailfrom'] . ' ' . $data['fromname'] . ' ' . vmText::$language->getTag() . '<br>' . $emailBody; vmdebug($msg); $return = true; } else { if (JFactory::getApplication()->get('mailonline', 1)) { if (JVM_VERSION >= 4) { $mailer = new \Joomla\CMS\Mail\MailTemplate($mailtemplate, $app->getLanguage()->getTag()); $mailer->addTemplateData($data); $mailer->addRecipient($data['email']); $return = $mailer->send(); } else { $return = JFactory::getMailer()->sendMail($data['mailfrom'], $data['fromname'], $data['email'], $emailSubject, $emailBody); } } }
to

Code Select Expand

// Send the registration email.
if (VmConfig::showDebug() and $debug_email == 'debug_email')
{
$msg = 'Registration Debug mail active, no mail sent. The mail to send subject ' . $emailSubject . ' to "' .   $data['email'] . '" from ' . $data['mailfrom'] . ' ' . $data['fromname'] . ' ' . vmText::$language->getTag() . '<br>' . $emailBody;
vmdebug($msg);
$return = true;
}
else
{
$return = true;

if (JFactory::getApplication()->get('mailonline', 1))
{
try {
if (JVM_VERSION >= 4)
{
$mailer = new \Joomla\CMS\Mail\MailTemplate($mailtemplate, $app->getLanguage()->getTag());
$mailer->addTemplateData($data);
$mailer->addRecipient($data['email']);

$return = $mailer->send();
}
else
{
$return = JFactory::getMailer()->sendMail(
$data['mailfrom'],
$data['fromname'],
$data['email'],
$emailSubject,
$emailBody
);
}
}
catch (\Throwable $e)
{

$return = false;

// Log technique
if (class_exists('\Joomla\CMS\Log\Log')) {
\Joomla\CMS\Log\Log::add(
'Registration mail failed for ' . ($data['email'] ?? '-') . ' : ' . $e->getMessage(),
\Joomla\CMS\Log\Log::WARNING,
'mail'
);
}
}

// Message to user
if (!$return) {
if (function_exists('vmWarn')) {
vmWarn("Confirmation e-mail not sent (e-mail adress / invalid domain).Your account is created, you can continue.");
} else {
$app->enqueueMessage("Confirmation e-mail not sent (e-mail adress / invalid domain).Your account is created, you can continue.", "warning");
}

}
}
}
so now when the e-mail domain is invalid, it does not crash the site but display a warning message.

Hope it helped
