I don't receive any email after form submitions. Is that possible that my SMTP server doesn't work?

FMP by default uses SMTP server mentioned in PHP settings (file php.ini). There are two ways to change default settings:
1. Reset value of "SMTP" parameter in php.ini. Contact your administrator or ISP and ask them how to do this.
2. In file "/forms/formprocessorpro.php" add line ini_set('SMTP','yourmailserver.com');
where 'yourmailserver.com' is your SMTP server. Preferably to insert it at the second line.
