In Magento1 when running under Windows you could set the SMTP Host and SMTP Port. In Magento 1 this is achieved by code similar to the following: ``` ini_set('SMTP', Mage::getStoreConfig('system/smtp/host')); ini_set('smtp_port', Mage::getStoreConfig('system/smtp/port')); ``` In Magento 2 there is no reference in the source-code anywhere to `system/smtp/host` or `system/smtp/port`
