+ Feature: specify "enable_long_queue_ids = yes" to enable
+ support for non-repeating queue IDs (also used as queue
+ file names). These queue IDs encode the time and inode
+ number with a safe alphabet of the 52 characters 0-9B-Zb-z.
+ The alphabet excludes vowels (AEIOUaeiou) to avoid creating
+ real words. The queue ID format is: time in seconds, time
+ in microseconds, 'z', inode number (the inode number is
+ encoded without using the 'z' character of the safe alphabet).
+ Turning on long queue IDs changes the width of the first
+ output column of the mailq (postqueue -p) command, and
+ changes the appearance of Postfix Message-ID headers to
+ queueID@myhostname. Files: global/file_id.[hc],

* Some postscreen(8) configuration parameters implement stress-dependent
behavior. This is supported only when the default value is stress-dependent
- (that is, it looks like ${stress?X}${stress:Y}). Other parameters always
- evaluate as if the stress value is the empty string.
+ (that is, "postconf -d parametername" output shows "parametername = $
+ {stress?something}${stress:something}"). Other parameters always evaluate
+ as if the stress value is the empty string.
* See "Tests before the 220 SMTP server greeting" for details about the
logging from these postscreen(8) tests.

+Incompatible changes with snapshot 20110320
+===========================================
+
+If you enable support for long queue file names, you need to be
+aware that these file names are not compatible with Postfix <= 2.8.
+If you must migrate to Postfix <= 2.8, you must first convert all
+long queue file names into short names, otherwise the old Postfix
+version will complain.
+
+The conversion procedure before migration to Postfix <= 2.8 is:
+
+ # postfix stop
+ # postconf enable_long_queue_ids=no
+ # postsuper
+
+Run the postsuper command repeatedly until it no longer reports
+queue file name changes.
+
+Major changes with snapshot 20110320
+====================================
+
+Support for long, non-repeating, queue IDs (queue file names). The
+benefit of non-repeating names is simpler logfile analysis, and
+easier queue migration (there is no need to run "postsuper" to
+change queue file names that don't match their message file inode
+number).
+
+Specify "enable_long_queue_ids = yes" to enable the feature. This
+does not change the names of existing queue files. See postconf(5)
+or postconf.5.html#enable_long_queue_ids for a detailed description
+of the differences with the old short queue IDs.
+
+This changes new Postfix queue IDs from the short form 0FCEE9247A9
+into the longer form 3Ps0FS1Zhtz1PFjb, and changes new Message-ID
+header values from YYMMDDHHMMSS.queueid@myhostname into the shorter
+form queueid@myhostname.
+
+See the note on "Incompatible changes" for a backwards migration
+procedure to convert long queue file names into a form that is
+compatible with Postfix <= 2.8.

Don't forget Apple's code donation for fetching mail from
IMAP server.
- Use queue ID (file name) based on inode number and enough
- (time or random) bits to avoid repetition in 10+ years.
-
Simplify postscreen logic: set the noforward flag if the
client made an unforgivable error. Individual "fail" flags
are needed only to avoid logging the same offense multiple

+/* safe_ultostr 3
+/* SUMMARY
+/* convert unsigned long to safe string
+/* SYNOPSIS
+/* #include <safe_ultostr.h>
+/*
+/* char *safe_ultostr(result, ulval, base, padlen, padchar)
+/* VSTRING *result;
+/* unsigned long ulval;

+/*
+/* unsigned long safe_strtoul(start, end, base)
+/* const char *start;
+/* char **end;
+/* int base;
+/* DESCRIPTION
+/* The functions in this module perform conversions between
+/* unsigned long values and "safe" alphanumerical strings
+/* (strings with digits, uppercase letters and lowercase
+/* letters, but without the vowels AEIOUaeiou). Specifically,
+/* the characters B-Z represent the numbers 10-30, and b-z
+/* represent 31-51.
+/*
+/* safe_ultostr() converts an unsigned long value to a safe
+/* alphanumerical string. This is the reverse of safe_strtoul().
+/*
+/* safe_strtoul() implements similar functionality as strtoul()
+/* except that it uses a safe alphanumerical string as input,
+/* and that it supports no signs or 0/0x prefixes.
+/*
+/* Arguments:
+/* .IP result
+/* Buffer for storage of the result of conversion to string.
+/* .IP ulval
+/* Unsigned long value.
+/* .IP base
+/* Value between 2 and 52 inclusive.
+/* .IP padlen
+/* .IP padchar
+/* Left-pad a short result with padchar characters to the
+/* specified length. Specify padlen=0 to disable padding.
+/* DIAGNOSTICS
+/* Fatal: out of memory.
