Unable to submit your request Magento Contact Form Error

Question

I keep getting this error when trying to submit my contact form: "Unable to submit your request. Please, try again later"

I'm using default Magento contact form.

Does anyone know where to start with this? It was working a few days ago and now it's not.

I've also been having issues with sales emails sending.

Thanks in advance.

In the example below I tried to go to an order and click "send email" then I tired to fill out the contact form on the front end...

Answer 1

To expand on Marius his answer, if it's the mail server I suggest contacting the hosting company to set up a mailing server on your server or use Aschroder's SMTP extension to configure a SMTP connection

Answer 2

I had this exact same problem and error message. I also had the excellent SMTP Pro installed.

When I ran the SMTP self test via admin it sent the email successfully but still gave me a red error response. Also it would fail when sending an enquiry via the contact form.

For me, the problem was a conflict with the Ebizmarts MageMonkey extension.

According to the aschroder_smtppro.log

2014-10-10T00:09:57+00:00 DEBUG (7): Running SMTP Pro Self Test
2014-10-10T00:09:57+00:00 DEBUG (7): Checking config re-writes have not clashed.
2014-10-10T00:09:57+00:00 DEBUG (7): Detected overwrite conflict: Ebizmarts_Mandrill_Model_Email_Template
2014-10-10T00:09:57+00:00 DEBUG (7): Using Google Apps/Gmail Transport.
2014-10-10T00:09:57+00:00 DEBUG (7): Skipping raw connection test for non-SMTP options.
2014-10-10T00:09:57+00:00 DEBUG (7): Actual email sending test...
2014-10-10T00:09:57+00:00 DEBUG (7): Zend_Mail Object

As we aren't even using the Mandrill component of MageMonkey, removing the Ebizmarts_Mandrill.xml from /app/etc/modules resolved this conflict and now everything is working as expected.

The answer is simple. You don't have a mail server configured, or you are not linked correctly.
Or your e-mail template is wrong. If you have changed the e-mail template for the contact form try with the default one. If that works check the differences between the default one and yours.
[EDIT] The exception is thrown if something gors wrong in Zend_Mail_Transport_Sendmail::_sendMail() around these lines:

$result = mail(
            $this->recipients,
            $this->_mail->getSubject(),
            $this->body,
            $this->header,
            $this->parameters); 

IF you say the template file is there then the problem is with the mail server. Try to log the values in the code above, and "manually" test the mail function with the values you log and with other test values. This way you can see of the values are wrong or the mail server has a problem.
