PHP Mailer works - mail action did not send a email

Hi,I build a little Form that save only the Data.But I like to Inform a User by email that a new Entry is in the Database.

If I open administrator/index.php?option=com_config and go down to E-MailingAnd send a test email - this mail I gotbut not from the Form ?

Is there a Setting I need to set "use PHP Mailer" ?Thanks

You can enable the form Debug under the form Settings and that will show after the form is sent if the email has succeeded or not
