Validation email doesn't work

Hi all, in my site www.timbari.it/public a new user is registered but he doesn't receive any confirmation email, it was not able to post.

how can i fix that?

because the test button says that's all ok, but no mail received

Justoverclock

the test button says that's all ok, maybe the sender email must be the same of the smtp parameters?

Justoverclock that's usually required yes. But it depends on the service you use.

i'm using my hosting in siteground...anyway now works with the same mail as parameters.
