接收时间和发送时间

hechengjin

1. nsParseMailbox.cpp中
   
2. 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
   
3. 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）
   
4. 抓包先进行下面两个操作
   
5. 146 uid copy 2166 "&V4NXPpCuTvY-"
   
6. 146 OK COPY completed
   
7. 147 uid store 2166 +FLAGS (\Deleted \Seen)
   
8. * 5 FETCH (FLAGS (\Deleted \Seen) UID 2166)
   
9. 147 OK STORE completed
   
10. 
    
11. 后面再获取：
    
12. 7 UID fetch 1383299324 (UID RFC822.SIZE FLAGS BODY.PEEK[HEADER.FIELDS (From To Cc Bcc Subject Date Message-ID Received Priority X-Priority References Newsgroups In-Reply-To Content-Type)])
    
13. 
    
14. * 16 FETCH (UID 1383299324 FLAGS (\Seen) RFC822.SIZE 1738 BODY[HEADER.FIELDS (FROM TO CC BCC SUBJECT DATE MESSAGE-ID RECEIVED PRIORITY X-PRIORITY REFERENCES NEWSGROUPS IN-REPLY-TO CONTENT-TYPE)] {393}

41. 
    
42. 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。
    
43. 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。
    
44. nsParseMailbox.cpp
    
45. 读信页显示窗口时间的修改msghdrviewOverlay.js
    
46. 增加通过 x-richinfo-localizeddate-received 获取时间值
    
47. nsMimeHtmlEmitter.cpp
    
48. 中增加 x-richinfo-localizeddate-received  获取对 received中日期解析及获取
    
49. 关联字段的修改
    
50. nsMsgDBView.cpp
    
51. nsMsgDBView::CellTextForColumn
    
52. case 'd':  // date
    
53.   {
    
54.     rv = FetchDate(msgHdr, aValue,true);
    
55. 
    
56. 协议解析的修改
    
57. nsParseMailbox.cpp
    
58. nsParseMailMessageState:: ParseHeaders
    
59. 
    
60. case 'R': case 'r':
    
61. nsParseMailMessageState:: ParseFolderLine
    
62. nsParseMailMessageState:: ParseAFolderLine
    
63. nsImapMailFolder.cpp
    
64. nsImapMailFolder:: ParseAdoptedHeaderLine
    
65. nsImapMailFolder:: ParseMsgHdrs
    
66. 
    
67. IMAP请求的修改nsImapProtocol.cpp
    
68. #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
    
69. #define IMAP_DB_HEADERS "Priority X-Priority References Newsgroups In-Reply-To Content-Type"
    
70. #define IMAP_ENV_AND_DB_HEADERS IMAP_ENV_HEADERS IMAP_DB_HEADERS
    
71. 
    
72. 发送的请求
    
73. 7 UID fetch 1382926263 (UID RFC822.SIZE FLAGS BODY.PEEK[HEADER.FIELDS (From To Cc Bcc Subject Date Message-ID Received Priority X-Priority References Newsgroups In-Reply-To Content-Type)])

76. 
    
77. Set the variable:
    
78. mailnews.use_received_date = true (boolean)
    
79. 
    
80. If you are using a POP3 account, that should suffice.
    
81. 
    
82. For a IMAP account, you should set also:
    
83. mailnews.customDBHeaders = Received (string)
    
84. 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.
    
85. 
    
86. 
    
87. 扩展  通过mailnews.customDBHeaders开关

mailnews.display.date_senders_timezone; 为true 读信页会显示时区

1. mailnews/local/src/nsParseMailbox.cpp
   
2. 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
