Magento 2 SMTP settings

Question

I've got a fresh magento 2 installation on a virgin test system, but I can't find the settings for a smtp connection. How do you manage email communication in magento 2?

Answer 1

Ok, sorry for that. The problem was that I didn't realise that magento uses the php-mail funtion, which calls the mail-mathod of my debian installation. I first needed to install and configure postfix (here the tutorial), and after that the php.ini tutorial here. Then it worked like intended!

Answer 2

Install extension from GmailSmtpApp here and replace Model/Transport.php with below changes to configure setting for Gmail SMTP service.

<?php
/**

 * Copyright © 2015 MagePal. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace MagePal\GmailSmtpApp\Model;



class Transport extends \Zend_Mail_Transport_Smtp implements \Magento\Framework\Mail\TransportInterface
{
    /**
     * @var \Magento\Framework\Mail\MessageInterface
     */
    protected $_message;

    /**
     * @var \Magento\Framework\App\Config\ScopeConfigInterface
     */
    protected $_scopeConfig;

    /**
     * @param MessageInterface $message
     * @param null $parameters
     * @param \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
     * @throws \InvalidArgumentException
     */
    public function __construct(\Magento\Framework\Mail\MessageInterface $message, \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig)
    {
        if (!$message instanceof \Zend_Mail) {
            throw new \InvalidArgumentException('The message should be an instance of \Zend_Mail');
        }

        $this->_scopeConfig = $scopeConfig;

         $smtpHost = $this->_scopeConfig->getValue('system/gmailsmtpapp/smtphost', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
         $smtpConf = array(
            'auth' => $this->_scopeConfig->getValue('system/gmailsmtpapp/auth', \Magento\Store\Model\ScopeInterface::SCOPE_STORE),
            'ssl' => 'SSL',
            'username' => $this->_scopeConfig->getValue('system/gmailsmtpapp/username', \Magento\Store\Model\ScopeInterface::SCOPE_STORE),
            'password' => $this->_scopeConfig->getValue('system/gmailsmtpapp/password', \Magento\Store\Model\ScopeInterface::SCOPE_STORE)
         );
        parent::__construct($smtpHost, $smtpConf);
        $this->_message = $message;


    }

    /**
     * Send a mail using this transport
     *
     * @return void
     * @throws \Magento\Framework\Exception\MailException
     */
    public function sendMessage()
    {
        try { 
            parent::send($this->_message);
        } catch (\Exception $e) {
            error_log($e);
            throw new \Magento\Framework\Exception\MailException(new \Magento\Framework\Phrase($e->getMessage()), $e);
        }
    }
}

Thanks.

I found this SMTP on Github. It supports 21 different SMTP servers such as Gmail, Hotmail, O2 Mail, Office365, Mail.com, Send In Blue, AOL Mail Orange, GMX, Outlook, Yahoo, Comcast, or Custom SMTP - own SMTP server.
