-The message ID has 3 parts: tttttt-pppppp-ss. Each part is a number in base 62.
-The first part is the current time, in seconds. The second part is the current
-pid. Both are large enough to hold 32-bit numbers in base 62. The third part
-can hold a number in the range 0-3843. It used to be a computed sequence
-number, but is now the fractional component of the current time in units of
-1/2000 of a second (i.e. a value in the range 0-1999). After a message has been
-received, Exim ensures that the timer has ticked at the appropriate level
-before proceeding, to avoid duplication if the pid happened to be re-used
-within the same time period. It seems likely that most messages will take at
-least half a millisecond to be received, so no delay will normally be
-necessary. At least for some time...
+lifetime of Exim, and is changing for Exim 4.97.
+The previous change was in about 2003.
+
+Detail for the pre-4.97 version is here in [square-brackets].
+
+The message ID has 3 parts: tttttt-ppppppppppp-ssss (6, 11, 4 - total 23 with
+the dashes). Each part is a number in base 62.
+[ tttttt-pppppp-ss 6, 6, 2 => 16 ]
-There is a modification when localhost_number is set. Formerly this was allowed
-to be as large as 255. Now it is restricted to the range 0-16, and the final
-component of the message id becomes (localhost_number * 200) + fractional time
-in units of 1/200 of a second (i.e. a value in the range 0-3399).
+The first part is the current time, in seconds. Six chars is enough until
+year 3700 with case-sensitive filesystes, but will run out in 2038 on
+case-insensitive ones (Cygwin, Darwin - where we have to use base-36.
+Both of those are in the "unsupported" bucket, so ignore for now).
-Some not-really-Unix operating systems use case-insensitive file names (Darwin,
-Cygwin). For these, we have to use base 36 instead of base 62. Luckily, this
-still allows the tttttt field to hold a large enough number to last for some
-more decades, and the final two-digit field can hold numbers up to 1295, which
-is enough for milliseconds (instead of 1/2000 of a second).
+The second part is the current pid, and supports 64b [31b] PIDs.
-However, the pppppp field cannot hold a 32-bit pid, but it can hold a 31-bit
-pid, so it is probably safe because pids have to be positive. The
-localhost_number is restricted to 0-10 for these hosts, and when it is set, the
-final field becomes (localhost_number * 100) + fractional time in centiseconds.
+The third part holds sub-second time, plus (when localhost_number is set)
+the host number multiplied by a number large enough to keep it away from
+the time portion. Host numbers are restricted to the range 0-16.
+The time resolution is variously 1, 2 or 4 microseconds [0.5 or 1 ms]
+depending on the use of localhost_nubmer and of case-insensitive filesystems.
+
+After a message has been received, Exim ensures that the timer has ticked at the
+appropriate level before proceeding, to avoid duplication if the pid happened to
+be re-used within the same time period. It seems likely that most messages will
+take at least half a millisecond to be received, so no delay will normally be
+necessary. At least for some time...
-Note that string_base62() returns its data in a static storage block, so it
-must be copied before calling string_base62() again. It always returns exactly
-6 characters.
+Note that string_base62_XX() returns its data in a static storage block, so it
+must be copied before calling string_base62_XXX) again. It always returns exactly
+11 (_64) or 6 (_32) characters.
There doesn't seem to be anything in the RFC which requires a message id to
start with a letter, but Smail was changed to ensure this. The external form of
way. It appears in the initializing code in exim.c. The macro MESSAGE_ID_LENGTH
must also be changed to reflect the correct string length. The queue-sort code
needs to know the layout. Then, of course, other programs that rely on the
-message id format will need updating too. */
