SMTP fail to send email

I already setup my gitlab, however i cant receive any email or send an email to new users for register here some test i have done through console Capture

Hi @rey98 !

It seems like you have set up SSL, which seems to have not been working properly. I will need some more details than this.

  1. Can you share your gitlab.rb file?
  2. The ‘/etc/hosts’ file
  3. Check the status of selinux and firewalld
  4. The steps how you created the certificate and the certificated which are generated on the client machine

Please provide the above information and I might be able to tell you why is it not working.
