Komento not sending comment notification emails.

Hello,

I'm using Komento free but im thinking in buying it, because i really like the component.
But i have a serious problem with the mails when an user does a comment of one of my articles.

First of all, you need to know i'm using Joomla! 2.5 with the last version of Komento free.
My site is serfelices.org.

Well, i have 2 kind of users: Public users and Authors.
The authors can create articles for public users, and everyone can comment in any article. But if the one who comments is a Public user (actually, it's a guest, he doesn't need to be logged), then the administrator (me) needs to approve the comment in order to be shown.

Komento sends any mail BUT this kind of mails.
I checked all my configurations and i think they're OK. I also checked the cronjob, it's configured just like the tutorial.

I will attach some screenshots of my configuration.

As you see, the MailQ says the mails are sent, but i never recieve them.

Please, can you help me with this problem?

Thanks in advice, have a nice 2014!
