接收时间和发送时间
nsParseMailbox.cpp中int nsParseMailMessageState::ParseHeaders ()这个函数对返回的日期串的解析，对于126邮件从一个文件夹移动到另一个文件夹中的操作，不知为什么传过来的时间总是当前的时间
造成每次移动后，原来的日期都不能正常显示，目前只是判断了如果 received 中的时间比 date中的时间新的话，则使用date的时间，具体为什么会传当前时间还要分析（实际过程：要移动的邮件copy完成后，会重新获取一下新位置的邮件信息，而126返回的串的日期是不正确的）
抓包先进行下面两个操作
146 uid copy 2166 "&V4NXPpCuTvY-"
146 OK COPY completed
147 uid store 2166 +FLAGS (\Deleted \Seen)
* 5 FETCH (FLAGS (\Deleted \Seen) UID 2166)
147 OK STORE completed
后面再获取：
7 UID fetch 1383299324 (UID RFC822.SIZE FLAGS BODY.PEEK)
* 16 FETCH (UID 1383299324 FLAGS (\Seen) RFC822.SIZE 1738 BODY {393}

即在移动邮件后，新邮件夹中每次重新从服务端获取新到的邮件的头信息，而不是读取本地的邮件信息，而从服务端返回的信息中日期是不正确的。
如何触发获取新邮件消息头的，本地又是如何存储的，移动的过程中除了在服务端执行命令外，本地双进行了哪些操作/ 这个过程能不能不请求服务端的消息头。
nsParseMailbox.cpp
读信页显示窗口时间的修改msghdrviewOverlay.js
增加通过 x-richinfo-localizeddate-received 获取时间值
nsMimeHtmlEmitter.cpp
中增加 x-richinfo-localizeddate-received获取对 received中日期解析及获取
关联字段的修改
nsMsgDBView.cpp
nsMsgDBView::CellTextForColumn
case 'd':// date
{
rv = FetchDate(msgHdr, aValue,true);
协议解析的修改
nsParseMailbox.cpp
nsParseMailMessageState:: ParseHeaders
case 'R': case 'r':
nsParseMailMessageState:: ParseFolderLine
nsParseMailMessageState:: ParseAFolderLine
nsImapMailFolder.cpp
nsImapMailFolder:: ParseAdoptedHeaderLine
nsImapMailFolder:: ParseMsgHdrs
IMAP请求的修改nsImapProtocol.cpp
#define IMAP_ENV_HEADERS "From To Cc Bcc Subject Date Message-ID Received " 最后加上一个空格，要不和后面的连接在一起了
#define IMAP_DB_HEADERS "Priority X-Priority References Newsgroups In-Reply-To Content-Type"
#define IMAP_ENV_AND_DB_HEADERS IMAP_ENV_HEADERS IMAP_DB_HEADERS
发送的请求

Set the variable:
mailnews.use_received_date = true (boolean)
If you are using a POP3 account, that should suffice.
For a IMAP account, you should set also:
mailnews.customDBHeaders = Received (string)
In this way, the "Received" column will not be identical to the "Date" column anymore; now it shows the reception date on your mail server, that is generally considered to be a better choice.
扩展通过mailnews.customDBHeaders开关

mailnews.display.date_senders_timezone; 为true 读信页会显示时区mailnews/local/src/nsParseMailbox.cpp
int nsParseMailMessageState::ParseHeaders () 目前的方案：收件箱里显示的是smtp服务器的时间,即received里的时间,而已发送里显示的是当前系统的时间即 data 里的时间,当两者不一致时会有出入.
另外收件箱里,只有data里的时间比smtp里的时间还早时,会显示data时间,这个是为了防止在移动邮件时,老是出现时间为执行当前操作的时间,原来的时间都找不到了,具体细节还要研究 D:\svn\Client\ThinkMail_ClientWin_2013\trunk\src\thinkmail\mailnews\mime\src\mimedrft.cpp
