Laravel env and mailing info

Question

I want to know is that possible I use one of my host emails instead of gmail in laravel or not?

Issues

1. When I use Gmail info as mailing

   MAIL_DRIVER=smtp
   MAIL_HOST=smtp.gmail.com
   MAIL_PORT=465
   [email protected]
   MAIL_PASSWORD=MAIL_PASSWORD
   MAIL_ENCRYPTION=ssl
   [email protected]
   MAIL_FROM_NAME="CUSTOM_NAME"
   

it works.

But when I try to use my host email it doesn't

MAIL_DRIVER=smtp
MAIL_HOST=HOSTING_SERVER
MAIL_PORT=HOST_PORT
MAIL_USERNAME=MY_HOST_EMAIL
MAIL_PASSWORD=MY_HOST_EMAIL_PASSPORD
MAIL_ENCRYPTION=null

2. Even with providing sender info in my env file emails always send by gmail address to users and not provided email address.

   [email protected]
   MAIL_FROM_NAME="CUSTOM_NAME"
   

Any idea?
