修改配置文件：/etc/gitlab/gitlab.rb

### Email Settings
 gitlab_rails['gitlab_email_enabled'] = true
 gitlab_rails['gitlab_email_from'] = 'gitlab@xxx.com.cn'
 gitlab_rails['gitlab_email_display_name'] = 'xx GitLab'
# gitlab_rails['gitlab_email_reply_to'] = 'noreply@example.com'
# gitlab_rails['gitlab_email_subject_suffix'] = ''

### GitLab email server settings
###! Docs: https://docs.gitlab.com/omnibus/settings/smtp.html
###! **Use smtp instead of sendmail/postfix.**

 gitlab_rails['smtp_enable'] = true
 gitlab_rails['smtp_address'] = "smtp.exmail.qq.com"
 gitlab_rails['smtp_port'] =
 gitlab_rails['smtp_user_name'] = "xxzz@xx.com

################################################################################

# user['username'] = "git"
# user['group'] = "git"
# user['uid'] = nil
# user['gid'] = nil

##! The shell for the git user
# user['shell'] = "/bin/sh"

##! The home directory for the git user
# user['home'] = "/var/opt/gitlab"

 user['git_user_email'] = "gitlab@xxx.com.cn"

执行重新配置命令：

gitlab-ctl reconfigure

然后重新启动gitlab：

gitlab-ctl restart

所有步骤执行完成，然后我们可以测试一下，配置是否成功！

a.首先进入gitlab控制台

gitlab-rails console

b.执行如下命令，发送测试邮件

Notify.test_email("8080@qq.com","主题","正文").deliver_now

收到邮件，大功告成！
