      Hi, All,

      When my postfix+courier received/sent an email, it will have a file
      which name like this:
      1373311807.V805I31d1928M179657.zeta.veecall.com,S=1456:2,ST

      Can someone explain to me how to understand this name? I mean for
      example like the above one, what is the meaning of "1373311807" and
      "V805I31d1928M179657"?

      In the maillog, postfix use mail ID like "C0A3BC258D", is there a
      relation between this ID and the filename?

      More interested is the last part of the filename. It seems related with
      the status of the mail. (Read/Unread/..etc.). Can you explain more on this?

      Thank you for help.

      Gao

          There is no relation between the postfix queueid and the final
          filename used for maildir storage.

          For all the mind-numbing details, use your favorite search engine to
          look for "maildir specification".
