Net::SMTPFatalError (553 Mail from must equal authorized user)
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。
