Hello!! I installed Gitlab CE Omnibus Package on Ubuntu 16.04 droplet. Im a newbie in all respects on mail and smtp. On the gitlab page it says that you can configure Gmail by editing the /etc/gitlab/gitlab.rb file with this:

 gitlab_rails['smtp_enable'] = true
 gitlab_rails['smtp_address'] = ""
 gitlab_rails['smtp_port'] = 587
 gitlab_rails['smtp_user_name'] = ""
 gitlab_rails['smtp_password'] = "password"
 gitlab_rails['smtp_domain'] = ""
 gitlab_rails['smtp_authentication'] = "login"
 gitlab_rails['smtp_enable_starttls_auto'] = true
 gitlab_rails['smtp_tls'] = false
 gitlab_rails['smtp_openssl_verify_mode'] = 'peer'

I did that and then sudo gitlab-ctl reconfigure

But it’s not sending any emails. Should i have postfix or manage some sort of certs also?

Thanks in advanced.

I have seen reports of gmail refusing smtp connections from some IP addresses in our ranges (along with those of other cloud providers). I would recommend checking your log files for any error messages /var/log/gitlab/gitlab-rails/production.log is a good place to start.

If you are seeing messages there indicating that gmail is refusing the connection I would recommend using a service like sendgrid to send mail from your droplet. The service is free for up to 12,000 emails per month. I use them in my own projects and have never encountered a problem.

If you are seeing a different error message indicated please share it here so we can dig into it.

    Hi Luis,
    Someone just tried to sign in to your Google Account from an app that doesn’t meet modern security standards.

    We strongly recommend that you use a secure app, like Gmail, to access your account. All apps made by Google meet these security standards. Using a less secure app, on the other hand, could leave your account vulnerable. Learn more.
