Fixes possible DoS vulnerability. Thanks to Sven Mueller and Florian + Weimer for the solution. +- Added new options for adding X-Envelope-From and (optionally) X-Envelope-To + headers to messages before SA processing. The idea is to help SA process any + blacklist/whitelist to/from directives on the actual sender/recipients instead + of the possibly bogus envelope headers. Use --seh or --set-envelope-headers + to enable setting both headers, or use --sef or --set-envelope-from to enable + only X-Envelope-From. If added, spampd attempts to remove the X-Envelope-To + header after SA processing to preserve BCC recipient anonymity, but enabling + this header may still expose recipient information. See man page for more + details. This patch was originally submitted by Sven Mueller, was slightly + modified, and the --sef option was added. + +######## + +2.21 (23-Oct-05) (unreleased) +- fixed SA version check on alphanumeric version strings. Stops the annoying + Perl warning messages in the mail log. Thanks to Sven Mueller for the fix. + +######## + +2.20 (05-Oct-04) +- added support for SpamAssassin version 3. spampd should now support all + SA versions (tested with 2.6.3 and 3.0.0). +- removed --add-sc-header feature. It is now redundant with SA v2.6 ability + to (almost fully) customize headers, which v3 improves on. If anyone + really needs this feature, please let me know. +- added --nodetach option to prevent daemon process backgrounding. Patch + provided by Urban Petry. Can be useful for win32/cygwin. +- if --debug is specified, Net::Server log level is increased to 4 (debug) + to provide some more info in the log (can be useful for diagnosing + user/permission issues). Thanks to Urban Petry for idea. +- the message sender (From header) is now included in the log along with message + ID, recipient, and scoring info. Thanks to Roland Koeckel for the patch. + +######## + +2.13 (24-Nov-03) +- SA debug messages redirected from STDERR (warn) to syslog. Thanks to Roland + Koeckel for the suggestion. + +######## + +2.12 (15-Nov-03) +- fixed bug related to Sys::Syslog where we needed to escape % signs in + Message IDs. Thanks to Jeffrey W. Collyer and Yann Grossel for the bug reports. +- minor performance improvement in SpamPD::Client using buffered write to send + message data. Thanks to Sam Horrocks for the tip. +- fixed error condition when an error response ([4|5]xx) was returned after a + DATA command was sent. Thanks to Rodrigo Ventura for bug reports about this. + +######## + +2.11 (15-Jul-03): +- fix for occasional corrupted message headers which caused blank messages + (seemed to have only affected certain malformed spam mail). +- added --logsock option for syslog socket. Defaults to 'unix' except for + HP-UX and SunOS (Solaris) which I'm told prefer 'inet'. + +######## + +2.10 (01-Jul-03): +- added optional 'X-Spam-Checked-By: {hostname}' header, where {hostname} is, + theoretically, the name of the machine doing the message scanning. New + options --add-sc-header and --hostname=name control this behavior. + +######## + +2.00 (10-Jun-03): +- major rewrite of how mail is handled internally. spampd now takes no + responsibility for the mail at any point, instead acting as a transparent + proxy between the originating and the destination servers. That is, the + servers speak to each other through spampd so final mail delivery + occurs only when the destination server acknowledges receipt of the data. + Idea based on smtpprox by Bennett Todd (http://bent.latency.net/smtpprox/). + Unfortunately this breaks the ability to redirect the mail based on spam + score, since scoring happens after all recipients have been specified and + accepted. But, it is much cleaner and safer than the previous method. + +- new architecture doesn't store the mail data in memory any more. Message + is still written to memory before scanning by SpamAssassin, but messages + larger than the --maxsize to be scanned won't eat up a bunch of memory. + From smtpprox documentation by Bennet Todd: + "it [spampd] stores the body of the message in an unlinked file + under /tmp, which should be a tmpfs; this prevents the allocation + overhead associated with large strings (often 2-3x) and ensures that + space will be returned to the OS as soon as it's not needed." + +- as a bonus feature, LMTP is now supported by virtue of spampd's transparency. + +- added a timeout check around the socket operations as suggested in the + Net::Server docs. Added new parameter to control this: --childtimeout=n + where n is number of seconds. + +- added a timeout check around the message processing (spam checking) routines + to guard against a SpamAssassin hang. Added new parameter to control + this: --satimeout=n where n is number of seconds. If a timeout (or error) + occurs while processing, the mail is still passed on unless the new --dose + (die-on-sa-errors) paramater is given. + +- added --children=n parameter to specify how many child + servers to spawn and maintain. Default is 5 children (plus + one parent). + +- now uses Net::Server::PreForkSimple instead of PreFork. (Tried utilizing the + advanced children pool features of PreFork but either couldn't figure it out + or they're kinda broken. If anyone has experience here, please let me know.) + +- improved logging including the Message-ID, recipients, 100ths precision + on spam score, processing time, and file size. Logging format now better + resembles that of spamd (which hopefully means spamd log analysis tools can be + made to work with spampd easily). + +- removed dependencies on Net::SMTP, Net::SMTP::Server::Client, and Error + modules. + +- host/port and relay host/port can both be specified as xx.xx.xx.xx:nn in + the --host and --relayhost parameters, or as individual parameters (--host, + --port, --relayhost, --relayport). + +# The next 3 items are ideas/patches by +# Kurt Andersen, +# Agilent Technologies Postmaster +# Global Messaging Team, Agilent Technologies + +- added optional support for Time::HiRes for more accurate processing time + reporting in the log (automatically loaded if Time::HiRes is available). + +- added optional logging of which SA rules matched a message. New option is + --log-rules-hit or --rh for short. + +- Added auto HPUX OS detection for syslog loggging + "(for some reason HPUX chokes on using the 'unix' socket type)." + +# Thanks Kurt! + +- added much more verbose spampd logging when using the --debug option. + +- 3 parameters are now deprecated but accepted for backwards compatability: + --dead-letters, --heloname, and --stop-at-threshold + +- added shorthand choice for some options: + --aw for --auto-whitelist; --L for --local-only; --a for --tagall + --u for --user; --g for --group; --p for --pid + --d for --debug; --h for --help; + +- documentation updates + +- licensing change due to use of Bennet Todd's code (to GNU GPL from Perl + Artistic). + +######## + +1.0.2 (13-Apr-03): +- added 'local-only' parameter to pass on to SA which turns off all + network-based tests (DNS, Razor, etc). + +######## + +1.0.1 (3-Feb-03): +- fixed minor but substantial bug preventing child processes + from exiting properly since the counter wasn't being incremented (d'oh!). + Thanks to Mark Blackman for pointing this out. + +- fixed typo in pod docs (Thx to James Sizemore for pointing out) + +######## + +Changes to assassind (1.0.0 initial release of spampd - May 2002): +A different message rewriting method (using + Mail::SpamAssassin::NoMailAudit instead of Dave Carrigan's + custom headers and Mail::Audit); +Adding more options for message handling, network/protocol options, + some options to pass on to SpamAssassin (such as whitelist usage); +More orientation to being used as a content filter for the + Postfix MTA, mostly by changing some default values; +Documentation changes; + +## EOF ##
