似乎是你的 ISP 封掉了你的主机的 25 端口？

“不能用web登录邮箱”，具体是指无法访问 webmail 呢，还是登录 webmail 后无法发出邮件？具体什么错误信息？

如果你的服务器上没有任何对方的 smtp 连接日志，那应该是对方根本没有连接到你的服务器。这种情况有几种可能：

- 你的邮件域名的 DNS 设置有问题，没有指向正确的服务器地址。
- 你的公司内部防火墙没有做正确的端口转发。

用output.sql不能批量导入密码名称等，很不方便，怎么实现批量导入呢？安装LDAP是否可行？

自己按格式写SQL就行吧，我看这里有密码格式说明

访问/mail都没问题，访问/iredadmin 502 ，我看uwsgi服务是启动的

手工安装软件包：uwsgi-plugin-python2，然后重启 uwsgi 服务应该就ok了。

软件包的名字原本是 uwsgi-plugin-python，后面在 epel 仓库里被改名了，导致这个问题。

环境已经架设完成，主机名称：mail.abc.com
目前已经做了mail.abc.com的A记录解析到服务器IP：1.2.3.4
使用mail.abc.com可以正常的使用smtp、pop、imap等。
不过为了便于管理使用，需要对域名再做如下解析：smtp.abc.com、pop.abc.com、imap.abc.com
以前使用的是poste.io系统，直接使用cname解析到mail.abc.com就可以
但是在更换为iredmail后，如此操作，在本地foxmail中正常，可在服务器上，用phpmailer发信的时候，如果SMTP地址填写的是smtp.abc.com，就会出现SMTP: connect faild错误，必须填写mail.abc.com。
已经在多台服务器上测试过，配置环境：
smtp地址：smtp.abc.com
账号：admin@ddd.com（属于其中一个域）
密码：xxxx
端口：587
加密方式：TLS

Iredmail 安装成功后，登陆后隔天无法登陆

Web admin panel (iRedAdmin):
Roundcube webmail:

Iredmail 安装成功后，上述两项均可成功登陆，但是，隔天无法登陆。无法连接服务器，网页无法打开。登陆时，有提示ssl 未安装，连接不安全。此外，无其它提示。搜索网上，没有可行的方法解决。如此数次折腾，折腾近一个月，仍然无法解决。

另，尝试安装ssl,安装好后，根据Iredmail 提供的方法配置好相关配置文件后，
发现，原来上面两项都可以登陆的，现在无法登陆了。没有任何错误提示。下面是操作时参考的相关链接。

https://docs.iredmail.org/use.a.bought. … -ssl-cert】

请问张工 ， 是否有简单有效的办法解决这些错误?本人安装的是免费版本。不知道是否是因为免费版本，所以有这些bug. 如果是，是否购买了收费版本后，这些问题都将不再存在？ 请简单讲免费版本和收费版本的差异。
谢谢

经常收到一下培训类的垃圾邮件，请问下，该如何解决？

需要修改/etc/nginx/templates/roundcube.tmpl

你的服务器估计是内网的
需要要做端口映射

hi, 無色天空 ,版主.
我在 iredMail 0.9.8 版本時, 更改無效:

/etc/nginx/templates/roundcube.tmpl
location ~ ^/webmail/(bin|config|installer|logs|SQL|temp|vendor)($|/.*) { deny all; }

location ~ ^/webmail/(CHANGELOG|composer.json|INSTALL|jsdeps.json|LICENSE|README|UPGRADING)($|.*) { deny all; }

# Block plugin config files and sample config files.
location ~ /mail/plugins/.*/config.inc.php.* { deny all; }

# Block access to plugin data
location ~ /mail/plugins/enigma/home($|/.*) { deny all; }

# Redirect URI `/mail` to `/mail/`.
location = /mail {
    return 301 /mail/;
}

location ~ ^/webmail(.*)\.php$ {         
    include /etc/nginx/templates/hsts.tmpl;
    include /etc/nginx/templates/fastcgi_php.tmpl;
    fastcgi_param SCRIPT_FILENAME /var/www/roundcubemail$1.php;
}

location ~ ^/webmail(.*) {
    alias /var/www/roundcubemail$1;
    index index.php;
}

#不使用自動 redirect webmail網址 ;
location /webmail {
               rewrite ^/* /webmail last;
        }

## 不自動redirect 到 mydomain.com/mail  ; 把index.html 取消
mv /var/www/html/index.html  /var/www/html/index.html.orig

請指導一下 , 願聞其詳.
謝謝.
