默认情况下，gitlab用qq邮箱注册是发送不出确认邮件的。

下面说说gitlab配置腾讯企业邮箱

# vim /etc/gitlab/gitlab.rb
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.exmail.qq.com"
gitlab_rails['smtp_port'] = 465 
gitlab_rails['smtp_user_name'] = "support@ttlsa.com"
gitlab_rails['smtp_password'] = "www.ttlsa.com"
gitlab_rails['smtp_domain'] = "ttlsa.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] = "support@ttlsa.com"

重新加载配置

# gitlab-ctl reconfigure
