FluxCP Mailing system trouble

[Checkmath]

I cant seem to make it work, whether its SMTP or pure php, never seems to happen
with errors: SMTP connect() failed. when I use tsl or ssl at ports 587 and 465 respectively

and when I use php, I get: Could not instantiate mail function.

By the lack of people talking about those errors I assume its something very dumb, so my first question is, do I have to use any 3rd part software to let the flux send the e-mails?

At this very moment I'm using:

 

Quote

    'MailerFromAddress'            => '[email protected]',        // The e-mail address displayed in the From field.
    'MailerFromName'            => 'Squadfight - Hora do Show!',            // The name displayed with the From e-mail address.
    'MailerUseSMTP'                => true,                    // Whether or not to use a separate SMTP server for sending mail.
    'MailerSMTPUseSSL'            => true,                    // Whether or not mailer should connect using SSL (yes for GMail).
    'MailerSMTPUseTLS'            => false,                    // Same as above SSL setting, but for TLS.  This setting will override the SSL setting.
    'MailerSMTPPort'            => 465,                    // When MailerUseSMTP is true: SMTP server port (mailer will default to 25).
    'MailerSMTPHosts'            => 'smtp.gmail.com',                    // When MailerUseSMTP is true: A string host or array of hosts (e.g., 'host1' or array('host1', 'backuphost')).
    'MailerSMTPUsername'        => '[email protected]',                    // When MailerUseSMTP is true: Authorized username for SMTP server.

With right password right below.
About the ports, they are open.

Everything above is correct, looks like a hoster restriction against spam. Are you using any shared web hosting, or cPanel hosting? Usually such companies just lock mailing functions for avoiding spam.

Gmail is very picky with where it allows smtp connections from. It has a special table somewhere that lists what you need to configure with specific ports and smtp host. 

From memory your setup looks fine, though.
