I'm use WordPress 3.9.1 Multisite and your plugin 1.0.8 version. I'm adding the informations (name, port, login etc.) but all time in the test:
SMTP connect() failed.
Why? With the informations (name, port, password and etc.) works with the 3.8 WordPress.
What is the problem?
After plugin update, wordpress write one error, in easy-smtp.php line 112. But i dont know why.
