Roundcube 發送沒有主題的電子郵件
我最近設置了一個郵件伺服器,其中包含
postfix
和dovecot
。昨天我添加了nginx
和roundcube
混合。SPF、DKIM、DMARC、rDNS 記錄全部完成。Gmail 將我的郵件視為有效郵件並將其發送到我的收件箱。一切正常。除了一件煩人的小事。當我使用 Android 的內置 MUA 或其他 MUA 時,一切都很好。當我想使用圓形立方體發送郵件時,問題就開始了。郵件仍然經過驗證並正確發送,但沒有主題。不知何故,roundcube 正在失去主題欄位並在沒有主題的情況下發送我的電子郵件。
我連續 7 個小時一直在尋找答案,但似乎我是世界上唯一遇到此問題的人。這讓我覺得我的伺服器或配置有問題,但我四次檢查了我的所有配置,但我仍然一無所知。
任何幫助都將非常有用。在此先感謝您的時間。
我的郵件伺服器在一個具有 768MB RAM 的 OpenVZ 機器上,執行 CentOS 7 Minimal。後綴版本:2.10.1 Dovecot 版本:2.2.10 Roundcube 版本:1.1.0

我的 Roundcube 配置摘錄在
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'; $config['preview_pane'] = true;
我找到了解決我自己問題的方法。
以下是 program/steps/mail/sendmail.inc 中的第 507-513 行。
// encoding subject header with mb_encode provides better results with asian characters if (function_exists('mb_encode_mimeheader')) { mb_internal_encoding($message_charset); $headers['Subject'] = mb_encode_mimeheader($headers['Subject'], $message_charset, 'Q', "\r\n", 8); mb_internal_encoding(RCUBE_CHARSET); }
這是提到
$headers['Subject']
變數的兩個地方之一。另一個是設置變數的第 196 行。由於我和我的客戶都與亞洲字元無關,因此我決定將這段程式碼塊註釋掉,看看會發生什麼,瞧!受試者開始工作。似乎圓形立方體有一個奇怪的錯誤。我希望有一天這會對某人有所幫助。
