1. 編輯/etc/gitlab/gitlab.rb文件（加到文件最後面就好了）。以QQ企業郵箱為例：

gitlab_rails[‘smtp_enable‘] = true

gitlab_rails[‘smtp_address‘] = "smtp.exmail.qq.com"

gitlab_rails[‘smtp_port‘] = 465

gitlab_rails[‘smtp_user_name‘] = "[email protected]"

gitlab_rails[‘smtp_password‘] = "******"

gitlab_rails[‘smtp_authentication‘] = "login"

gitlab_rails[‘smtp_enable_starttls_auto‘] = true

gitlab_rails[‘smtp_tls‘] = true

gitlab_rails[‘gitlab_email_from‘] = ‘[email protected]‘
 

有的教程可能會說去改/opt/gitlab/etc/gitlab.rb，是錯的，一切以官網文檔為準

2. 重新配置gitlab

gitlab-ctl reconfigure

3. 通過命令行測試郵件是否發送成功（也可以不測）

gitlab-rails console

irb(main):003:0> Notify.test_email(‘[email protected]‘, ‘Message Subject‘, ‘Message Body‘).deliver_now

配置gitlab通過smtp發送郵件
