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!
