Question Mail service settings

[Maria Eugenia Cabanas G]

I know it is something elementary for some of you. help please. I have a contact form and the corresponding PHP file to send an email with the data of the form to an email of the page. Everything seems to work fine, but the mail is not sent, I have to fix something in the settings of the mail service for the PHP mailer to work?

thanks
