IMAP Server Compliance

  • Checkpoint: checkpoint parameter works. When issuing a CHECK command in all sessions, their state looks identical.
  • \Recent: Exactly one session sees a new message as \Recent - no more and no less.
  • Atomic flags: Flags and keywords can be added/removed in multiple sessions without one session dropping changes made by other (own_flags test)
  • Expunge fetch: If message is expunged in one session, can another session that still sees the message fetch its contents?
    • Yes: Yes, everything can be fetched
    • Cached: Only cached data can be fetched. Message header or body can't be.
    • No: Nothing but flags can be fetched.
  • Expunge store: If message is expunged in one session, can another session update its flags?
    • Yes: Yes, and a 3rd session also sees the change
    • Session: Yes, but a 3rd session won't see the change
    • Delayed: Yes, but a 3rd session won't see any changes until EXPUNGEs are reported

    • Ignored: STORE command replies OK, but no change is made
    • No: STORE command replies NO
  • Failures (failures/total): Number of failures using [:ImapTest/ScriptedTests:scripted tests]. These numbers may not be exact all the time, because the tests are still changing.

    • Failure groups: Each test belongs to a wider group of tests, typically testing a command or part of a command. If this count is low but individual command failure count is high, it probably means that the server has failed to implement wrong only a couple of commands.
    • Base fails: Number of individual base IMAP4rev1 protocol commands that failed.
    • Ext fails: Number of individual IMAP extension commands that failed. Extensions not supported aren't included in the numbers.
