Setup In order to test this, you'll need to setup your moodle to send emails, reCAPTCHA enabled, support email and no-reply email set. SMTP configuration - I suggest installing MailCatcher and just add 127.0.0.1:1025 to smtphosts setting in Site administration > Server > Email > Outgoing mail configuration Still on that page, set No-reply address to a valid email address. Note: Ensure the service is running during the test by running the command mailcatcher . ReCAPTCHA - You'll need to setup site and secret keys in Site administration > Plugins > Authentication > Manage authentication . To obtain those keys you need to generate it at Google reCAPTCHA . Support email set in Site administration > Server > Supportcontact Test contact site support page Without logging in, click on the in the footer and then click Contact site support link. Test the form validation, trying to submit without any data. Make sure you see Required validation message in all fields, except for the Security question . Now fill the form and try to submit without answering the reCAPTCHA (Security question). Make sure you get a " Failed reCAPTCHA challenge, try again. " validation message. Answer the security question (reCAPTCHA) field and click Submit . Make sure you are redirected to the Site homepage and see a confirmation message. Look the MailCatcher page http://127.0.0.1:1080/  in your browser and make sure you have received an email: Make sure the From email is the same of the no reply address. Make sure the To email is the same of the support email setting. Make sure the Subject is "Support contact message: The subject you have entered in the form" Make sure the information in the email body is the same you have entered in the form. Make sure there is a warning below the subject of the email, which warns you that the user who sent the email  was not logged in. Now log in as admin. Go to the contact support page again. Repeat the test above, the only differences should be that: the Name and Email address are pre-filled and you are not able to edit. you do not see the warning about the user not being logged in between the subject and email lines. Go to Site administration > Server > Support contact and set the Support page to https://moodle.com/contact/support/ Click on the in the footer and then click "Contact site support" link. Make sure you don't see the contact page and you are redirected to moodle's support page in a new window/tab. Remove the Support page . Update the smtphosts setting in Site administration > Server > Email > Outgoing mail configuration so that it uses an invalid port (eg add a 1 to the end) and save. Go to the contact site support page again, fill the form and submit. Make sure you are redirected back to the support form and see an error message that it could not be sent. Also make sure all of the information you previously filled in has been re-populated in the form. Now remove the value for  the smtphosts setting in Site administration > Server > Email > Outgoing mail configuration and save. Click on the in the footer and then click "Contact site support" link. Make sure you do not see the support form when the page loads. Make sure you do see a message on the page that you can't submit a request, and make sure it also lists the support email address. Mouse over the support email address and make sure it links to a mailto link for the email address displayed on the page. Log out, then click on the in the footer and then click "Contact site support" link. Make sure you see the same thing as you saw in step 26, but importantly make sure that the email address section is not shown on the page.
