Something’s not quite right

Hi Alexander, I’m trying to set Global SMTP up on WP 4.4.8 running on PHP 7.0.16. My observations are these: The plugin does not work at all when network activated. When used as MU-plugin the following happens: ALL constants need to be defined in config.php! As soon as any one of them (including those termed optional) is missing, Global SMTP quietly dies, and I get a WP error screen to the effect that I shouldn’t be doing what I’m doing… The trouble is specifically with GLOBAL_SMTP_PORT. If I put define('GLOBAL_SMTP_PORT', '465') , then Global SMTP tells me GLOBAL_SMTP_PORT should be an number. If, on the other hand, I put define('GLOBAL_SMTP_PORT', 465) , then Global SMTP again quietly dies. GLOBAL_SMTP_DEBUG didn’t make me any wiser, nothing showed up in the logs. Using the Check Mail plugin, mail did get sent – just not over SMTP… Perhaps you could have a look? Would be nice to have this working. The idea looks good to me!
