A customer of mine has a Joomla website with several forms. When submitting these forms an email is sent to my customer with the content. Unfortunately the preset values ("value if empty") are sent as well. Is there a way to remove this values before the mail is sent? The data is processed after the mail and for now these preset values are removed by hand which is rather time consuming. Furthermore I'd like to replace all new lines in the values with spaces before sending the mail.
