<p>Global SMTP is a utility plugin designed to easily configure SMTP for WordPress by adding a set of constants to your <code>wp-config.php</code> file.</p>
<p>When used with multisite, the configuration is applied network wide. This is often handy to install as a “must use” plugin.</p>


Global SMTP

Works with WP 4.4.2

This is the only SMTP plugin I found that works excellent with Multisite installed WordPress. And supports TLS, SSL, and don't use database and very fast!



Lightweight plugin, Support Multisite
