Git GitLab 配置通过 smtp.163.com 发送邮件
配置 SMTP 发送邮件配置，使用 163 邮箱。
$ sudo vi /etc/gitlab/gitlab.rb
# Change the external_url to the address your users will type in their browser
external_url 'http://xxhost.com'
#Sending application email via SMTP
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "[email protected]"
gitlab_rails['smtp_password'] = "xxpassword"
gitlab_rails['smtp_domain'] = "163.com"
gitlab_rails['smtp_authentication'] = :login
gitlab_rails['smtp_enable_starttls_auto'] = true
发送不成功，·sudo gitlab-ctl tail`检查日志报错如下：

Google 大法后，错误码对应解释网易服务器 smtp 机器要求身份验证帐号和发信帐号必须一致，如果用户在发送邮件时，身份验证帐号和发件人帐号是不同的，因此拒绝发送。
修改 gitlab.rb，修改发信人和身份验证帐号一致，163 发信 OK。
