Joomla dont send mail

[gabinhaa.b50]

Hi,
Please can help me to configure the E-mail on Joomla?

I used:
Mailer : mailer PHP (and tried sendmail)
Mail from : mercenarios@mercenarios.x10.mx
From Name : Mercenarios Guilda
Sendmail Path : /usr/sbin/sendmail
SMTP Authentication : Yes (tried with No too)
SMTP Security : SSL
SMTP Port: 25
SMTP Username : mercenarios@mercenarios.x10.mx
SMTP Password : (password created to this e-mail)
SMTP Host : localhost

I created this mail mercenarios@mercenarios.x10.mx on cpanel.

Please help me to work it.

PS. I see other post: http://x10hosting.com/forums/free-hosting/80587-how-send-mails-joomla-site.html but dont work.
