Check the basic mail functionality by entering your email address here and clicking the button.

If no email is received, your setup might be broken. Check the following:

• If $GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] is set to mail or sendmail, TYPO3 tries to use the operating systems' sendmail application. There might be no such program installed.
• If $GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport'] is set to smtp, check if the data given in $GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_smtp_*'] is valid. Wrong data here results in faulty requests to the mail server. You can find the resulting messages in the mail server log.
