Hello, I have my pangolin working and I would like to configure sending emails, I did all the configuration following the documentation, but I am getting some errors:

My configuration file with the email session:

email:
  smtp_host: "smtp.myhost.com.br"
  smtp_port: 587
  smtp_user: "no-reply@myhost.com.br"
  smtp_pass: "mypassword"
  no_reply: "no-reply@myhost.com.br"

I don't know if it could have something to do with my pangolin domain which is pangolin.myhost.net.br
It is different from my email server
