1. 配置邮箱
sudo vi /etc/gitlab/gitlab.rb
这里我使用的qq邮箱，在邮箱设置里打开POP3/SMTP服务，并保存好16位授权码。
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] =
"smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] =
"******@qq.com"
gitlab_rails['smtp_password'] = "授权码"
gitlab_rails['smtp_domain'] =
"smtp.qq.com"
gitlab_rails['smtp_authentication'] =
"login"
gitlab_rails['smtp_enable_starttls_auto'] =
true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] =
'******@qq.com'
修改上面的邮箱地址和验证码，其它的不要动。
保存好后重启 gitlab-ctl reconfigure
2.
测试配置是否成功：
执行 gitlab-rails console进入控制台。
发送一封测试邮件：Notify.test_email('收件人邮箱', 'title',
'body').deliver_now
结果如下：
Notify#test_email: processed outbound mail in 0.8ms

前面都正常，最后报了错。看起来前面的配置是没有问题的。
多方查找，是DNS的问题，自动获取DNS改为手动配置，填8.8.8.8。
继续测试发送邮件成功，问题解决。

-------------------------------------------------------------------------------------
原因是文件/etc/gitlab/gitlab.rb
里面的git_user_email和smtp_user_name不一致，解决办法是：
sudo gedit /etc/gitlab/gitlab.rb
将下面内容修改到文件里面，重复的就注释掉：
gitlab_rails['smtp_user_name'] = "(你自己的邮箱前缀)@163.com"
gitlab_rails['gitlab_email_from'] = "(你自己的邮箱前缀)@163.com"
gitlab_rails['gitlab_email_reply_to'] =
"(你自己的邮箱前缀)@163.com"
user["git_user_email"] = "(你自己的邮箱前缀)@163.com"
SMTP配置
1.修改gitlab.rb
sudo gedit /etc/gitlab/gitlab.rb
将下面内容加到文件里面：
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "(你自己的邮箱前缀)@163.com"
gitlab_rails['smtp_password'] = "(163邮箱设置的授权码！授权码！授权码！)"
gitlab_rails['smtp_domain'] = "163.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = false
gitlab_rails['gitlab_email_from'] = "(你自己的邮箱前缀)@163.com"
gitlab_rails['gitlab_email_reply_to'] =
"(你自己的邮箱前缀)@163.com"
user["git_user_email"] = "(你自己的邮箱前缀)@163.com"
这里一定要注意！！！注意！！！
smtp_user_name，gitlab_email_from，gitlab_email_reply_to和git_user_email建议一致，不然会出现：
SMTPFatalError (553 Mail from must equal authorized
user)
和
SMTPAuthenticationError (535 Error: authentication
failed)
只要内容没错，基本就不会有问题。
2.重新配置gitlab
sudo gitlab-ctl reconfigure
3.重启服务
sudo gitlab-ctl restart
完成。
