html mail not send

Question

I want sent email with Html tags, I install mailsystem and htmlmail modules, according to some tutorial that I read I provide tpl .

anyway The main problem is when I select HTMLMailSysytem in Site-wide default MailSystemInterface class no email sending, but when I put it in DefaultMailSystem mail sent, I try to find out why this happened in my custom module I try

$result = drupal_mail('cdigitdev', 'message_key', $to, user_preferred_language($user), array('body' => $body, 'subject' => $subject, 'headers' => array('Cc' => $header_cc, 'Bcc' => $header_bcc,'Content-Type' => 'text/html; charset=UTF-8; format=flowed'), $from, TRUE));
  ym($result);

The result is

But I didn't receive any email !!!!

I think this is related to mail server that when I try to send html server drupal(php) tell it is sended but I did not receive any thing , is it right?

Answer 1

For reasons I won't get in to, you should use an SMTP module and route your emails through a real email account. Check the SMTP Authentication Support module. Details from project page:

This module allows Drupal to bypass the PHP mail() function and send email directly to an SMTP server. The module supports SMTP authentication and can even connect to servers using SSL if supported by PHP.

Otherwise your emails can (and will) get blocked as spam.
