Roundcube 发送没有主题的电子邮件

Roundcube 发送没有主题的电子邮件

我最近设置了一个由postfix和组成的邮件服务器dovecot。昨天我添加了nginxroundcube。SPF、DKIM、DMARC、rDNS 记录都已完成。Gmail 将我的邮件视为有效邮件并将其发送到我的收件箱。一切正常。除了一件烦人的小事。

当我使用 Android 内置的 MUA 或其他 MUA 时,一切仍然正常。当我想使用 roundcube 发送邮件时,问题就开始了。邮件仍然经过验证并正确投递,但没有主题。不知何故,roundcube 丢失了主题字段并发送了没有主题的电子邮件。

我已经连续 7 个小时寻找答案,但似乎我是世界上唯一遇到此问题的人。这让我认为我的服务器或配置出了问题,但我仔细检查了所有配置,但仍然一无所知。

任何帮助都将非常有用。提前感谢您的时间。

我的邮件服务器位于具有 768MB RAM 的 OpenVZ 盒上,运行 CentOS 7 Minimal。Postfix 版本:2.10.1 Dovecot 版本:2.2.10 Roundcube 版本:1.1.0

我的 Roundcube 配置摘录如下config/config.inc.php

$config['debug_level'] = 5;
$config['db_dsnw'] = 'mysql://user:pass@localhost/database';
$config['default_host'] = 'tls://localhost';
$config['default_port'] = 993;
$config['smtp_server'] = 'tls://localhost';
$config['smtp_port'] = 587;
$config['ip_check'] = true;
$config['identities_level'] = 3;
$config['des_key'] = 'some key';
$config['mime_types'] = '/usr/share/nginx/html/roundcube/mime.types';
$config['preview_pane'] = true;

我找到了我自己的问题的答案。

以下是 program/steps/mail/sendmail.inc 中的第 507-513 行。

// encoding subject header with mb_encode provides better results with asian characters
if (function_exists('mb_encode_mimeheader')) {
    mb_internal_encoding($message_charset);
    $headers['Subject'] = mb_encode_mimeheader($headers['Subject'],
        $message_charset, 'Q', "\r\n", 8);
    mb_internal_encoding(RCUBE_CHARSET);
}

这是提到变量的两个地方之一$headers['Subject']。另一个是设置变量的第 196 行。

由于我和我的客户都与亚洲字符无关,我决定注释掉这段代码块,看看会发生什么,然后瞧!主题开始工作了。看来 roundcube 有一个奇怪的错误。我希望这有一天能对某人有所帮助。
