Did you make sure that sending mails from your webserver is possible in general?
Therefore please create a small file "mailtest.php" on your webspace with the following content:
- Code: Alles auswählen
$bitReturn = mail(
echo "sending a mail ".($bitReturn ? "succeeded" : "failed");
Replace the mail-address "email@example.com" with your address and open the file with your webserver and post its' output.
If it reports "succeeded", we'll have to digg into your kajona-configuration. If it reports "failed", there's a problem with your webservers' configuration.
