SMTP ERROR: Failed to connect to server: With PHPMAILER in Dreamhost - phpmailer

Question

I can not send mail using the PHPMailer lib. My site is hosted on dreamhost,
with SMTP gmail I can send more properly to the configuration provided by the hosting the only return is:
SMTP ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: Name or service not known (0)
SMTP connect() failed.
My code:
<?php
date_default_timezone_set('Etc/UTC');
require 'vendor/phpmailer/phpmailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$name = trim(stripslashes($_POST['name']));
$from = trim(stripslashes($_POST['email']));
$subject = trim(stripslashes($_POST['subject']));
$message = trim(stripslashes($_POST['message']));
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Host = 'mail.example.com.br';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'e-mail#example.com';
$mail->Password = 'password';
$mail->SMTPSecure = 'tls';
$mail->Debugoutput = 'html';
$mail->isHTML(true);
$mail->setFrom($from, $name);
$mail->addReplyTo($from, $name);
$mail->addAddress('email#example.com');
$mail->Subject = $subject;
$mail->Body = $message;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

I managed to solve the problem, first replaces the e-mail sent to an e-mail sender#example.com own client, then tried some documentation of dreamhost, made the necessary changes, the code:
date_default_timezone_set('Etc/UTC');
require 'vendor/phpmailer/phpmailer/PHPMailerAutoload.php';
$subject = trim(stripslashes($_POST['subject']));
$name = trim(stripslashes($_POST['name']));
$from = trim(stripslashes($_POST['email']));
$body = trim(stripslashes($_POST['message']));
$mail = new PHPMailer;
$mail->isSMTP();
$mail->CharSet = 'UTF-8';
$mail->SMTPDebug = 1;
$mail->Host = 'mail.example.com.br';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'sender#example.com.br';
$mail->Password = 'password';
$mail->Debugoutput = 'html';
$mail->isHTML(true);
$mail->setFrom('sender#dexample.com.br', 'DontAnswer');
$mail->addReplyTo($from, $name);
$mail->addAddress('contact#example.com.br');
$mail->Subject = $subject;
$mail->Body = $body;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
In dreamhost documentation says it should be repeated sending e-mail in setFrom () method; after these changes the form worked perfectly.
