X-Grey
Greylisting that's Fast

Prerequisites

X-Grey requires the following packages before you can install it:

• CGIlib, which is a library I wrote obstensibly to handle CGI scripts, but has grown considerably in the decade or so I've been using it.
• The GNU getopt library.
• The GNU readline package.
• libmilter and pthreads, but only if you are installing the Sendmail client.

Ch-ch-ch-changes

• 1.0.11 (2009-12-10)
  • Removed calls to exit() that should not have been there.
• 1.0.10 (2009-12-01)
  • GLD: Changed startup behavior—it now clears all counts from the saved state when starting up; use the --old-counts option to retain old behavior.
  • PFC: Added an extra space in logging output.
  • PFC: Changed some logging from level info to debug.
  • Make sure that we only log messages at or below our current logging level (set via the --log-level option).
  • Changed default system logging facility from local5 and local6 to mail; use the --log-facility option if you want to retain old facilities.
  • Added -Wextra and -ansi compiler options, and cleaning up code to remove warnings.
• 1.0.9 (2009-05-23)
  • Fixed a potential bug in the binary search routines. See Extra, Extra—Read All About It: Nearly All Binary Searches and Mergesorts are Broken for more information.
• 1.0.8 (2009-03-26)
  • Changed nearly all occurances of “gray” (regardless of case) to “grey” (yes, I'm anal like that).
  • Fixed the clean target in a few make files.
• 1.0.7 (2009-02-17)
  • GLD: I used to ignore EINTR when calling accept() for a bulk data transfer. This was not the thing to do. I also limit the time for accept() to 10 seconds.
• 1.0.6 (2008-04-16)
  • SMC: Set default stack to 64k
  • SMC: made sure calls to setrlimit(RLIMIT_STACK) actually takes effect (affect?) by calling exec() after setrlimit(); apparently, the pthread initialization takes place before main() is called, and thus limiting the stack size afterwards won't do any good
• 1.0.5 (2008-03-24)
  • Fixed a typo in the INSTALL file
  • SMC: Fixed a bug where SMTP AUTH users would still get greylisted
• 1.0.4

  • MCP: if it can't find the pager program in interactive mode, uses the internal pager
  • SMC: set default stack to 1M
  • Added version information to each program
  • Made sure all fields in the packets were initialized before calculating the CRC
  • Some more documentation written
• 1.0.1 (2007-11-03)
  • Fixed datatypes relating to the network protcol on 64bit systems
