SMTP settings for email issue

[syeddsherazi]

I have setup the self host panel on heroku. And then added the following for smtp:

SMTP_ADDRESS=smtp.gmail.com
SMTP_PORT=587
SMTP_DOMAIN=gmail.com
SMTP_AUTHENTICATION=plain
SMTP_USERNAME=username
SMTP_PASSWORD=password
MAILER_SENDER_EMAIL=myemail

But I don't believe it's working. Once I create an account on the dashboard panel I don't receive any email for confirmation. Also I keep on resending the email and it doesnt work:

If I create any email inbox then also at the end the domain isnt attached. Instead email forwarding format is like: 70d5a1df3389e43b6eb475da452bd4ed@false
