不配置SMTP都无法工作了
目前的版本Gitlab 16.9.0，管理员在创建用户的时候，管理员无法给用户指定初始密码。初始密码只能以邮件的形式，发送到用户的邮箱。
因此有了此篇博文，为我们的Gitlab服务器做好正确的SMTP配置。
找到Gitlab的config文件夹
如果您的Gitlab，是根据我们的文章安装的，那么gitlab.rb文件就是在这个位置：
volumes:
- '/mnt/disk5t/data/gitlab.amihome.cn/config:/etc/gitlab'
就是docker-compose.yml文件中配置的第一条映射，就是Gitlab容器中的config文件所在的位置
列出config文件夹下的全部文件：
root@dev-server:/mnt/disk5t/data/gitlab.amihome.cn/config# ls -l
total 204
-rw------- 1 root root 151884 Feb 25 06:35 gitlab.rb
-rw------- 1 root root 19095 Feb 26 07:27 gitlab-secrets.json
-rw------- 1 root root 505 Feb 25 06:35 ssh_host_ecdsa_key
-rw-r--r-- 1 root root 173 Feb 25 06:35 ssh_host_ecdsa_key.pub
-rw------- 1 root root 399 Feb 25 06:35 ssh_host_ed25519_key
-rw-r--r-- 1 root root 93 Feb 25 06:35 ssh_host_ed25519_key.pub
-rw------- 1 root root 2590 Feb 25 06:35 ssh_host_rsa_key
-rw-r--r-- 1 root root 565 Feb 25 06:35 ssh_host_rsa_key.pub
drwxr-xr-x 2 root root 4096 Feb 25 06:38 ssl
drwxr-xr-x 2 root root 4096 Feb 25 06:35 trusted-certs
查看gitlab.rb
Gitlab在安装成功后，SMTP部分的配置如下图：
直接编辑gitlab.rb
在Gitlab容器里，发送测试邮件
下边是完整的过程：
root@dev-server:/home/david/files# docker exec -it gitlab.amihome.cn /bin/bash
root@gitlab:/# gitlab-rails console
--------------------------------------------------------------------------------

说明邮件发不出去，是我们的SSL证书校验失败了。
在给邮件服务器正确配置SSL证书之后，再次测试。直至成功。
完整输出如下：
root@dev-server:/home/david/files# docker exec -it gitlab.amihome.cn /bin/bash
root@gitlab:/# gitlab-rails console

去poste.io的后台，给邮件服务器配置SSL证书
