vi cgi-bin/openwebmail/etc/templates/zh_TW.您的語系/composemessage.template
2. 找到下列的程式碼
url += "&to=" + escape (document.composeform.to.value);
url += "&cc=" + escape (document.composeform.cc.value);
url += "&bcc=" + escape (document.composeform.bcc.value);
3. 將上面這3行改成下面這樣
url += "&to=" + document.composeform.to.value;
url += "&cc=" + document.composeform.cc.value;
url += "&bcc=" + document.composeform.bcc.value;
