这是我的结尾在/config/environment/production.rb中，这对我来说是有效的。

I just recently install GitLab v5.0 on an Ubuntu 12.04 server and am now having issues with email notifications. I can't get GitLab to send any emails of any kind.

I've got my config/environments/production.rb file setup to use sendmail as the transport service:

config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true

And I can manually use sendmail successfully from the shell as described here: http://scratching.psybermonkey.net/2011/03/sendmail-how-to-test-sending-email.html

My config/gitlab.yml file is setup with the following email setting:

email_from: gitlab@myops.com

I've read that it could be a problem with Sidekiq not running so I ran the following command but nothing has changed.. I still can't send emails:

$ sudo -u git -H bundle exec rake sidekiq:start RAILS_ENV=production
$ ps aux |grep -i sidekiq
git       2791  2.1  4.2 206476 86620 pts/0    Sl   14:45   0:23 sidekiq 2.7.5 gitlab [0 of 25 busy] 

Which indicates to me that Sidekiq is indeed running... what else could be the issue here? There doesn't seem to be much documentation on GitLab's wiki regarding email settings unfortunately...

I found the following error being logged in sidekiq.log:

Any ideas?

This is my entries at the end in /config/environment/production.rb and that is working for me.
