I just depoly a LAMP + Mantisbt 2.25.2
everthing is fine but i have problem with email config.
i just copy the email config part from config_inc.php.sample as below and write it down in config_inc.php
i fill in everything and make sure is right.
whatever i go do admin page to test mail, or i reset user password to send mail, it doesn't work.
Since it doesn't show any error log (or i can't find these log) it just bothered me for days.
iknow where did i miss, can you help me?

--- Email Configuration ---

$g_phpMailer_method = PHPMAILER_METHOD_MAIL; # or PHPMAILER_METHOD_SMTP, PHPMAILER_METHOD_SENDMAIL
$g_smtp_host = 'localhost'; # used with PHPMAILER_METHOD_SMTP
$g_smtp_username = ''; # used with PHPMAILER_METHOD_SMTP
$g_smtp_password = ''; # used with PHPMAILER_METHOD_SMTP
$g_webmaster_email = 'webmaster@example.com';
$g_from_email = 'noreply@example.com'; # the "From: " field in emails
$g_return_path_email = 'admin@example.com'; # the return address for bounced mail
