請教關於squirrelmail簡體繁體亂碼問題

請教關於squirrelmail簡體繁體亂碼問題

兩個用戶假如都是簡體中文環境或者都是繁體中文環境,相互發郵件正常,但一方簡體環境,另一方繁體環境時,收發的郵件都是亂碼,需要改成相應的環境才能正常顯示,有什麼辦法讓系統自動轉換嗎?

自己將自己的語言設置正確.

不要在英文設置下發其他語言的郵件. 也不要這樣轉發

台灣和大陸的公司共用一個郵件系統,沒辦法啊

你們用的什麼郵件系統哦
沒採用UTF-8的編碼呀

postfix

我自己寫了一個patch，加入了charset detection功能，會依照郵件內的Content-Type或subject選擇合適的編碼，回覆和看附件時都會用同樣的encoding.....前提php要打開output_buffering.....如小弟的劣作有任何何bugs煩請告知，謝謝

將.po文件都轉換為utf-8編碼，並將配置文件全改為utf-8格式就不會出現亂碼了。
具體涉及到如下文件：
conf/config.ini.php的default_charset
function/i18n.php的lang[]和lang[]
