1.修改gitlab.rb配置项

目录：/etc/gitlab/gitlab.rb

修改：

gitlab_rails[smtp_enable] = true

gitlab_rails[smtp_address] = ""

gitlab_rails[smtp_port] = 465

gitlab_rails[smtp_user_name] = "xxxx@"

gitlab_rails[smtp_password] = "xxx"【授权码，去对应邮箱设置】

gitlab_rails[smtp_domain] = ""

gitlab_rails[smtp_authentication] = "login"

gitlab_rails[smtp_enable_starttls_auto] = true

gitlab_rails[smtp_tls] = true

gitlab_rails[gitlab_email_from] = xxxx@

user[git_user_email] = "xxxx@"

注意port端口配置成465以前的25端口阿里云已经关闭了

2.重启gilab配置

修改后执行gitlab-ctl reconfigure

3.进入rails控制台测试邮件发送

gitlab-rails console
