In the new version of the dude
is to send email notification?
or have to use parallel software to it?
Someone tells me a way to send the notification?

What new version of the dude are you taking about?

Actually I'm wondering how do I send email notifications. I saw here in the forum using the blat, but tested and did not work! Anyone know another way to send email?

If you are talking about 4.0beta3 it can do that. Just add it in 'Notifications' there is type 'email', but it does not support smtp authentication. Either you need your own server so you can add the Dude ip in a list where it can send without being authenticaded or use the smtp server of the recipient.
