### Email Settings
gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = '******@163.com'
gitlab_rails['gitlab_email_display_name'] = 'Curiouser163SMTPServer'
gitlab_rails['gitlab_email_reply_to'] = '*****@163.com'
gitlab_rails['gitlab_email_subject_suffix'] = 'Gitlab'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "******@163.com"
gitlab_rails['smtp_password'] = "******"
gitlab_rails['smtp_domain'] = "163.com"
