This module extends the capabilities of Magento 2 mailing by smtp host configuration.

A new mail transport type is added to the system which takes care of transport of outgoing mails to a mail service provider.

Add the module to your composer file.

{
  "require": {
    "shockwavemk/magento2-module-mail": "dev-master",
    "shockwavemk/magento2-module-mail-smtp": "dev-master"
  }
}

Install the module with composer.

    composer update

On succeed, install the module via bin/magento console.

    bin/magento cache:clean
    
    bin/magento module:enable Shockwavemk_Mail_Base
    
    bin/magento module:enable Shockwavemk_Mail_Smtp

    bin/magento setup:upgrade

Transport and storeage configuration can be easily done via store config. Installed plug-ins for transport and storeage can be selected at this point.

In Adminhtml/Backend via store config

Stores > Configuration > Advanced > System > Mail Sending Settings

it is possible to configure the follwing settings, if "smtp" is selected in dropdown for "type" value.

• Host
• Port
• Authentication
• Username
• Password
• Ssl settings

The base mail module supports attachment sending. Magento2 does not support native file attachment handling, therefore you need to add some code on your own.
