CHANGES

This is the CHANGELOG for amavisd-milter.

20210103:
        amavisd-milter-1.7.2:

        Bug and compatibility fixies:
        - The SMTP_AUTH* attributes are missing in policy_bank.

        Thanks to: @damluk

20200906:
        amavisd-milter-1.7.1:

        Bug and compatibility fixies:
        - An empty sender must always be enclosed in angle brackets.

20190227:
        amavisd-milter-1.7.0:

        amavisd-milter has been moved from SourceForge to to GitHub.

        New features:
        - Fork after initializing milter socket.
        - Use client_name if available instead of hostname passed to xxfi_connect.
        - Generate amamvisd-milter.8 from AMAVISD-MILTER.md.

        Bug and compatibility fixies:
        - Fixed compiler warnings.
        - Converted indentation to spaces only.
        - Removed obsoleted file amavisd-milter.spec.

20190203:
        Generate amamvisd-milter.8 from AMAVISD-MILTER.md.

20190127:
        Spamassassin's RDNS_NONE check requires in the synthesized Received:
        header Forward-confirmed reverse DNS (FCrDNS) client name or "unknown"
        if the FCrDNS is not available.

        Sendmail sends the reverse DNS or IP address in square brackets both
        in the client_host argument and the {client_name} macro. If the client
        name is FCrDNS, the {client_reverse} macro is set to OK, otherwise to
        FORGED, TEMP or FAIL.

        Postfix sends a FCrDNS or "unknown" using the {client_name} macro.

        Thanks to: Florian Pritz <bluewind@xinu.at>

20190121:
        The milter socket is created before amavisd-milter is daemonized.
        This allows to return an error in case of impossibility to create
        the milter socket and package maintainers can adjust milter socket
        permissions immediatelly after the main process exits.

        Thanks to: Matus Uhlar

20190116:
        Removed obsoleted file amavisd-milter.spec.

        libmilter/mfapi.h not define true and false.

20101105:
        Fixed typo in aclocal/ax_path_milter.m4 which prevents using LDFLAGS
        on Debian.

        Bug fix - sendmail 8.14 introduces three new callbacks.

20090601:
        Compatibility fix - Debian installs libmilter.a to /usr/lib/libmilter.

        Thanks to: Simon Hobson <linux@thehobsons.co.uk>

20081205:
        amavisd-milter-1.4.0:

        New features:
        - Added new amavisd-milter option -q which sets milter socket backlog
          used by listen(2).
        - Local state directory (default /var/amavis) is tunable via configure
          option:
          --localstatedir=</DIR>              - absolute path to local state
                                                directory.
        - Working directory (default local state directory) is tunable via
          configure option:
          --with-working-directory=<SUBDIR>   - subdirectory of local
                                                state directory.
          --with-working-directory=</DIR>     - absolute path to working
                                                directory.

        Bug and compatibility fixies:
        - amavisd-milter convert CRLF to LF in mail body to support amavisd-new
          integrated DKIM signing and verification.
        - Fixed memory leak in fts_alloc() on Solaris.
        - Solaris doesn't have dirfd().
        - Solaris 9 and older doesn't have sem_timedwait.

20081109:
        Local state directory (default /var/amavis) is tunable via configure
        option: --localstatedir=<DIR>

        Working directory (default local state directory) is tunable via
        configure option:
        --with-working-directory=<SUBDIR> subdirectory of local state directory
        --with-working-directory=</DIR>   absolute path to working directory

20081108:
        Added new amavisd-milter option -q which sets milter socket backlog
        used by listen(2).

20081029:
        Compatibility fix - Solaris 9 and older doesn't have sem_timedwait.
        Use sem_trywait if sem_timedwait isn't available.

        Thans to: Henrik Krohns <hege@hege.li>

20081029:
        Memory leak in fts_alloc() on Solaris fixed.

        Luke Mewburn wrote:
          In examining the code, it appears that the implementation of
          fts_alloc() can leak the struct stat fts_statp if you're not using
          ALIGNBYTES() && ALIGN(), which I guess that Solaris doesn't have.
          Given that the leaked buffers are 160 bytes in size (184960/1156),
          I suspect that's sizeof(struct stat) and our culprit.

        Thanks to: Henrik Krohns <hege@hege.li>
        Submitted by: Luke Mewburn <luke@mewburn.net>

20081028:
        Compatibility fix - Solaris doesn't have dirfd().

        Thanks to: Henrik Krohns <hege@hege.li>

20080701:
        Sync fts_open.c with the NetBSD libc (upstream) fts.c, which brought
        in a few fixes, including one that looked like a potential memory leak.
        Thanks to: Luke Mewburn <luke@mewburn.net>

        Properly check -D option parameters.
        Thanks to: Henrik K <hege@hege.li>

20080310:
        Convert CRLF to LF in mail body, because sendmail send always CRLF,
        but amavisd-new requires that a message on a temporary file is in
        a native text format of a host's file system, i.e. with LF terminated
        lines on Unix or Linux.
        Thanks to: David Schweikert <david@schweikert.ch> and Mark Martinec
        <Mark.Martinec@ijs.si>

20070923:
        amavisd-milter-1.3.1

        Bug fixies:
        - Properly calculate timezone offset for synthesized Received header
          on platforms where gmtime() and localtime() returns the pointer to
          the same static struct.

20070923:
        Better explained -D option.

20070915:
        In mlfi.c:mlfi_envfrom() the gmtime() and localtime() call returns the
        pointer to the same static struct.  Thus pointers gt and lt are
        identical and the UTC offset is always +0000 which is bogus.
        Thanks to: Curtis Doty <curtis@greenkey.net>

20070902:
        amavisd-milter-1.3.0

        New features:
        - Implemented AM.PDP request attribute policy_bank (amavisd-new
          2.5.0 or higher is required).  Currently SMTP_AUTH, SMTP_AUTH_<MECH>
          and SMTP_AUTH<MECH>_<BITS> policy bank names are sent when the remote
          client is authenticated.
        - Added new amavisd-milter option -D client|server which allow
          personalized header or body modifications.

        Bug fixies:
        - fixed bug when amavisd communication buffer is growing.

        Compatibility:
        - properly get queue id when amavisd-milter is used with postfix.

        Performance:
        - improved performance under heavy load.

20070901:
        Performance optimization: use sem_timedwait instead of
        sem_trywait+sleep(1) for amavisd connection lock.
        Requested by: David Schweikert <david@schweikert.ch>

20070831:
        Added new amavisd-milter option -D client|server which allow
        personalized header or body modifications.
        Requested by: Brian C. Huffman <bhuffman@graze.net>

        Fixed bug when amavisd communication buffer is growing.
        Thanks to: Michael Moeller <mmoeller@kimchukmail.com>

20070729:
        Better compatibility with Postfix: it does give information about
        the queue-number only after the RCPT-TO-phase.
        Thanks to: David Schweikert <david@schweikert.ch>

20061219:
        amavisd-milter-1.2.1

        New features:
        - Implemented AM.PDP request attribute 'protocol_name'.
          Add folowing line to your sendmail.mc:

          define(`confMILTER_MACROS_ENVFROM', confMILTER_MACROS_ENVFROM`, r, b')

        Limited support for sendmail 8.12:
        - smfi_addheader() is used instead of smfi_insheader() for insheader
          and addheader AM.PDP responses. This works well with amavisd-new
          2.4.3 or newer.
        - smfi_progress() isn't called when amavisd-milter wait for amavisd-new
          communication socket.
        - AM.PDP response quarantine isn't implemented.

        Bug fixies:
        - add synthesized Received header for Spamassassin.
        - properly handle IPv6 client address.

20061217:
        Added support for IPv6 addresses.
        Thanks to: Mark Martinec <Mark.Martinec@ijs.si>

20061206:
        Limited support for legacy sendmail 8.12:
        - AM.PDP v2 response attribute quarantine isn't implemented.
        Thanks to: Adam Gibson <agibson@ptm.com>

20061203:
        Added info about user authentication to synthesized received header.
        Format of synthesized received header is now:

        Received: from <hello> (<rdns> [<ip>]) (authenticated bits=<bits>)
                by <hostname> (<rdns> [<ip>])
                with <protocol> (authenticated as <user>) id <qid>;
                <date>
                (envelope-from <sender>)

        Thanks to: Jo Rhett <jrhett@netconsonance.com>

20061113:
        Limited support for legacy sendmail 8.12:
        - amavisd-milter don't call smfi_progress when wait for amavisd-new
          communication socket.
        - amavisd-milter use smfi_addheader instead of smfi_insheader for
          insheader and addheader AM.PDP response attributes. This work well
          with amavisd-new 2.4.3 or newer. Older versions are affected with
          bug fixed on 20060714.

20061017:
        Implemented AM.PDP request attribute protocol_name.

        amavisd-milter adds Received header for the current connection to
        the mail file as the first line because without the most recent
        Received header, Spamassassin reports lots of false hits on rules
        checking where the message was received from.
        Thanks to: Jo Rhett <jrhett@netconsonance.com>

        NOTE: Please add these line to your sendmail.mc:

        define(`confMILTER_MACROS_ENVFROM', confMILTER_MACROS_ENVFROM`, r, b')


20061008:
        amavisd-milter-1.2.0

        Improved amavisd connection locking.  When amavisd connection is closed,
        lock is removed immediately.

20061004:
        Implemented AM.PDP protocol version 2.  New response attributes
        are version_server, insheader and quarantine.

        Tru64 portability fix: don't use variadic macros.

20060714:
        Fixed bug with addheader: amavisd-new assume that header is added
        to the end of headers but sendmail insert it before first occurence
        of the header with same name.
        Submitted by: Krzysztof Oledzki <ole@ans.pl>

20060616:
        Amavisd communication buffer is now dynamically allocated.
        MAXAMABUF is maximum buffer length, AMABUFCHUNK is initial length
        and reallocation step.  Buffer is allocated for every connection.

        Tru64 portability fix: replace missing daemon(8) function.

20060414:
        amavisd-milter-1.1.2

        MAXAMABUF is increased from 2048 to 65536 because it must be greater
        then confMAX_HEADERS_LENGTH which is usually set to 32768. If mail
        header is longer than MAXAMABUF, mail is permanently rejected with
        temporary fail return code and will never reach the recipents.

        Added new configure option --with-sendmail=<DIR> which change base
        directory in which are placed libmilter header files and library
        (e.q. /usr/local on FreeBSD when you using sendmail from ports).

20060125:
        amavisd-milter-1.1.1

        Portability release. amavisd-milter-1.1 now can be compiled on
        FreeBSD, NetBSD, OpenBSD, Linux and Solaris.  Please report
        success or problems on the users mailing list.

20060125:
        Linux and Solaris portability fix: sem_t is declared as pointer on
        *BSD but as structure on Linux and Solaris.

        Solaris portability fix: search sem_init in librt.

        Solaris portability fix: replace missing fts.h API.

20060124:
        amavisd-milter-1.1.0

        New features:
        - amavisd-milter can limit number of concurrent connections
          to amavisd-new
        - amavisd-milter is responsible to remove message work
          directory

20060124:
        README is now generated from amavisd-milter(8) manual page.

        Remove all files and directories in working directory because
        amavisd-new sometimes don't do it (e.q. when antivirus fail).

20060123:
        Limit maximum concurrent connections to amavisd:

            amavisd-milter -m 4 -M 600

        means that there is limit to maximum 4 concurrent connections to
        amavisd and wait maximum 10 minutes (10*60 sec) for connection to
        amavisd.  When connection isn't available, amavisd-milter sleep for
        1 sec.  Every minute of waiting is sendmail triggered via
        smfi_progress.  When time limit run out then amvisd-milter return
        temporary fail.

20060113:
        amavisd-milter-1.0.4

        Bugfix release.  Added manual page amavisd-milter(8).

        INCOMPATIBILITY with 1.0.3 and previous versions:

        Default working directory was changed from /var/amavis/tmp
        to /var/amavis to accordance with amavisd-new $helpers_home
        default value.  To go back to the previous behaviour run
        amavisd-milter with option -w /var/amavis/tmp

20060109:
        When stopping amavisd-new one (maybe not always just one) of milter
        threads amavisd-milter start to eat up a cpu time.
        Submitted by: Grzegorz Piszczek <grzegorz@piszczek.name>

        Fixed bug in mlfi_close(): amavisd-milter dies randomly due to
        segmentation fault.
        Submitted by: Grzegorz Piszczek <grzegorz@piszczek.name>

20051225:
        Added amavisd-milter(8) manual page.  README and website are
        synchronized with this manual page.

        Changed default working directory to /var/amavis (default value
        for amavisd-new helpers home directory).

20051204:
        Some users reports problem with ENOMEM in amavis_response().
        Consequently MAXAMABUF is increased from 1024 to 2048, amavis_request()
        and amavis_response() returns EOVERFLOW when buffer size isn't enough
        and truncated response is logged when debug level is >= 3.

20051202:
        Fixed default path to pidfile in README and website.
        Submitted by: Jerzy Sakol <jerzy.sakol@commgraf.pl>

20050829:
        Added amavisd-new configuration section to README.

20050701:
        amavisd-milter-1.0.3

        Bugfix release.  Properly set amavisd connection timeout.

20050701:
        Set amavisd_timeout instead of mlfi_timeout for -T option.
        Submitted by: Mr.Sompis Junsui <sompis.j@cdg.co.th>

20050701:
        Unlink old pid file on start.

20050605:
        amavisd-milter-1.0.2

        Bugix release.  Fix memory leak in mlfi_cleanup.

20050529:
        amavisd-milter-1.0.1

        Portability release.  Now can be compiled on Debian 3.0, Fedora FC2 and
        FC3, OpenBSD 3.4 and Solaris 9.  Tested on Sourceforge compile farm.
        Please report success or problems on the users mailing list:

        http://lists.sourceforge.net/lists/listinfo/amavisd-milter-users

20050522:
        Define EILSEQ on systems without it.

20050520:
        mkdtemp(3) compatibility function.

20050512:
        Initial version of README.

20050512:
        Better portability with autoconf macros from
        http://ac-archive.sourceforge.net/

20050510:
        strlcpy(3) compatibility function.

20050511:
        amavisd-milter-1.0.0

        First public release.  Fully tested on FreeBSD 5.3.
