Send a Test Email not works in Thold

[muriachi]

The link "Send a Test Email" not works for me, I tried all types Mail Services.
When I click in "Send a Test Email" the output of the page is:

Checking Configuration...
Creating Message Text...

This is a test message generated from Cacti. This message was sent to test the configuration of your Mail Settings.

Your email settings are currently set as follows

Method: Sendmail
Sendmail Path: /usr/sbin/sendmail

Sending Message...


any idea ?
thanks
