+1 on the request for this. GoDaddy installed your plugin to replace another WP mail plugin I had been using — but it’s generating the same “too many SMTP connections” error the old one did — and of course goDaddy insists it’s a plug in problem. On the phone with their level 2 support now. The debugging information in your plugin is great.
One solution they recommended to me was to use the fallback server in the plugin…but I have no way to test it.
