Newsletter mailer - no info to set it up

Hello everyone!
I need help in order to activate Newsletter mailer in my website.
On the Add-on page of Newsletter mailer was no info on how to set it up.
In the downloaded rar to. So i am not able to try if it works or not. So i need help.

I have fill all info under - > Settings - > Email - > 
Key Value
Sending emails
True
SMTP enabled
True
SMTP host

SMTP port
465
SMTP username

SMTP password

You do not need to set up anything. In the admin, under "customers" tab, look for Newsletter send. there you can send emails.

Yeah, I see the interface. 
That is not the issue. I am not able to send any email.
The addon is just showing this and that's it.

This is probably due to the settings you have set in Settings->Email
If your host has an emailserver, you should try:

SMTP Enabled  False
SMTP Host  localhost
SMTP Port  25
SMTP Username  
SMTP Password  **************** (passw is empty, but shows these asterix)```
Localhost should not need an authentication

All good now. 
Thanks, it was my mistake to put all info in to admin->settings->email 
Once I removed it, it all went well.
