Invalid SMTP connection URI

[pedrocarloto]

Hello!

I am not being able to install the latest version of this extension (0.1.15).
I get an error when updating:

Invalid SMTP connection URI. Must be in the form smtp(s)://username:password@hostname:port or smtp(s)://username@hostname:port.
SMTP password (Optional) Description

This is the same SMTP that I am currently using in production and follows the defines pattern.

Thank you.
