Using Gmail to send email

I’ve recently set up a Gitlab server on my own hardware, and I’m trying to get an account up and running. I do not have a working email server on this hardware and as such I’m trying to get the confirmation email to be sent using a Gmail account I’ve set up explicitly for this purpose. I’ve edited my gitlab.rb file file to include Gmail’s settings, but I still can’t get things to work. Any ideas?


gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = ""
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "<username>"
gitlab_rails['smtp_password'] = "<password>"
gitlab_rails['smtp_domain'] = ""
gitlab_rails['smtp_authentication'] = :plain
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true

For starters see the example in the documentation

I see that you have set authentication to :plain, whereas this should be a string according to docs. Try the settings above and report back.

In my stupidity, I forgot about the admin account. Now, I can create a user through there with no issue, which was why I opened up this topic in the first place. But, my problem still remains about sending out emails: it doesn’t work. I’ve updated my configurations with those sample configs although I’m still having issues, even after having Gitlab resend the confirmation email. Is there anything else I should try?

EDIT: Here’s something from the sidekiq.log file that could prove useful:

2015-05-03_19:15:42.35591 2015-05-03T19:15:42.355Z 5295 TID-7dajg WARN:

From the top of my mind:

  1. Check your firewall
  2. If you installed postfix check the queue with postqueue -p
  3. See /var/log/mail.log for any bounces
  4. See whether sidekiq has any error with gitlab-ctl tail sidekiq (gitlab-ctl tail for all logs)

Send a test mail from your server

echo test | mail -s test

Ok nice now we’re getting somewhere. Check this issue

I’ve taken the steps listed in both of your posts, but the echo test | mail -s test command does nothing. What firewall settings do I have to check, exactly? I’ve allowed port 25 and port 587, but I get some error in the log:

May  3 17:36:58 netbook-server postfix/smtp[19210]: 60424321061: to=<>,[]:587, delay=326414, delays=326413/0.25/0.24/0.03, dsn=5.7.0, status=bounced (host[] said: 530 5.7.0 Must issue a STARTTLS command first. m195sm23534424qhb.35 - gsmtp (in reply to MAIL FROM command))

At this point, since I’ve set up my user account, I guess this error is not crucial to be fixed, but it’d be nice to know everything is working.

Can you try the fix proposed in ?

gitlab-rails['smtp_ca_file'] = '/opt/gitlab/embedded/ssl/certs/cacert.pem'

It lives! Now I get email from the Gmail account I set up. Thanks! The fix was I think a combination of your suggested fix but also enabling access for less secure apps at this URL. I hope this fixes the issue for other people!

I’ve followed all the instruction from this post but I can’t send confirmation email through gmail account: my sidekiq log reports:

What’s the matter? Does gmail allows external application to send emails through their servers?

Is better to open a new dedicated thread?

Just another element: if I try to send a test email with swaks, with the following command, from my company smtp server

./swaks --to --auth --auth-user=mycompanyemail --auth-password=mycompanyemailpassword --server

I receive the email to

So, following these parameters, how can I configure gitlab-ce to send confirmation emails using my company smtp server?

Start with:

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = ""
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "mycompanyemail"
gitlab_rails['smtp_password'] = "mycompanyemailpassword"
gitlab_rails['smtp_domain'] = ""
gitlab_rails['smtp_authentication'] = "login"
