Finally, I have solved this issue.
Before the only language of the site was English and everything worked very well.
I'm using Drupal 8.3.7, and have the 8.x-1.0-beta2 version of the SMTP module.
After switching to multi-language, mailing does not work with the English language, and not for other languages. On the configuration page I have this message:

Disabled fields are overridden in site-specific configuration file.

Unable to send email. Contact the site administrator if the problem persists.

Solution:

The actual reason for this error is the newly implemented multilanguage feature.

I have applied the patch from the issue
Also first configure the smtp settings for the non default language.

Hi,

I am facing the issue with latest release of SMTP and Drupal core. And I'm not using multi-language but still getting error - SMTP Error: Could not connect to SMTP host.

Please review my issue - https://www.drupal.org/node/2920413

Thanks
