Erpnext Email explanation

Hello, im really confused about E-Mail sending and receiving in erpnext version 15.

So i configured my Email Account like this:


and my E-Mail DOmain like this:

i then created a user and gave him that specific email to access to, i also gav him Email permission for the “COmmunication” now when i go to Email inbox, i can send emails from there but they never actually get sent to my tst email. and also when i send emails to that email i was guessing it shows in my inbox and i can answer from there. but theres nothing happening, am i missing something?

Thank you in advance

Greetings
