Настройка SMTP сервера

Используется phpmailer, при отправке почты с сайта появлялась ошибка: SMTP Error: Could not connect to SMTP host.

Поменял порт в настройках на 25, теперь ошибка следующая:

SMTP Error: The following recipients failed: name@host.ru

Вот настройки:

...

$mail->Mailer = "smtp";

$mail->Host = "217.23.5.201";

$mail->CharSet = "UTF-8";

//$mail->Encoding = "base64";

$mail->Port = "25";

$mail->WordWrap = "300";

$mail->SMTPAuth = true;

$mail->Username = "support@host.ru";

$mail->Password = "pass";

$mail->AddReplyTo("support@host.ru","Техническая поддержка oboi20.ru");

$mail->AddAddress($to);

$mail->SetFrom("noreply@host.ru","Почтовый робот oboi20.ru");

...

Нужно настраивать как-то классы phpmailer'a?

В php.ini

Нужно что-то менять?
