Causes CLI errors because SERVER_NAME is not available

Every time I used WP-CLI, I got this error: Notice: Undefined index: SERVER_NAME

That’s because SERVER_NAME is not available via command line. There is a fix though.

Edit the file: postman-smtp/Postman/Postman-Mail/PostmanDefaultModuleTransport.php

Change this (line 37):

$sitename = strtolower ( $_SERVER ['SERVER_NAME'] );

To this:

$siteurl = parse_url( esc_url( site_url() ) );
$sitename = $siteurl['host'];

Works fine now ??
