gitlab-设置邮件SMTP以及GitLab收不到邮件的问题

1. 配置邮箱

sudo vi /etc/gitlab/gitlab.rb

这里我使用的qq邮箱，在邮箱设置里打开POP3/SMTP服务，并保存好16位授权码。

gitlab_rails['smtp_enable'] = true

gitlab_rails['smtp_address'] = "smtp.qq.com"

gitlab_rails['smtp_port'] = 465

gitlab_rails['smtp_user_name'] = "******@qq.com"

gitlab_rails['smtp_password'] = "授权码"

gitlab_rails['smtp_domain'] = "smtp.qq.com"

gitlab_rails['smtp_authentication'] = "login"

gitlab_rails['smtp_enable_starttls_auto'] = true

gitlab_rails['smtp_tls'] = true

gitlab_rails['gitlab_email_from'] = '******@qq.com'

修改上面的邮箱地址和验证码，其它的不要动。

保存好后重启 gitlab-ctl reconfigure

2. 测试配置是否成功：

执行 gitlab-rails console进入控制台。

发送一封测试邮件：Notify.test_email('收件人邮箱', 'title', 'body').deliver_now

结果如下：

Notify#test_email: processed outbound mail in 0.8ms

Sent mail to xxxx@qq.com (1.7ms)

前面都正常，最后报了错。看起来前面的配置是没有问题的。

多方查找，是DNS的问题，自动获取DNS改为手动配置，填8.8.8.8。

继续测试发送邮件成功，问题解决。

3.测试邮件提示

-------------------------------------------------------------------------------------

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。
