NAME

       sieve-dump - Pigeonhole's Sieve script binary dump tool

SYNOPSIS

       sieve-dump [options] sieve-binary [out-file]

DESCRIPTION

       The sieve-dump command is part of the Pigeonhole Project (pigeonhole(7)), which adds Sieve
       (RFC 5228) support to the Dovecot secure IMAP and POP3 server (dovecot(1)).

       Using the  sieve-dump  command,  Sieve  binaries,  which  are  produced  for  instance  by
       sievec(1),  can  be  transformed  into  a  human-readable textual representation. This can
       provide valuable insight in how the Sieve script is executed. This  is  also  particularly
       useful  to  view  corrupt  binaries that can result from bugs in the Sieve implementation.
       This tool is intended mainly for development purposes, so normally  system  administrators
       and users will not need to use this tool.

       The format of the output is not explained here in detail, but it should be relatively easy
       to understand. The Sieve binaries comprise a set of data blocks, each of which can contain
       arbitrary  data.  For  the  base  language  implementation  two blocks are used: the first
       containing a specification of all required language extensions and the  second  containing
       the  main  Sieve  program.  Compiled  Sieve programs are represented as flat byte code and
       therefore the dump of the main  program  is  a  disassembly  listing  of  the  interpreter
       operations. Extensions can define new operations and use additional blocks. Therefore, the
       output of sieve-dump depends greatly on the language extensions used  when  compiling  the
       binary.

OPTIONS

       -c config-file
              Alternative Dovecot configuration file path.

       -D     Enable Sieve debugging.

       -h     Produce  per-block  hexdump  output  of  the  whole  binary  instead  of the normal
              human-readable output.

       -o setting=value
              Overrides the configuration setting from  /etc/dovecot/dovecot.conf  and  from  the
              userdb with the given value.  In order to override multiple settings, the -o option
              may be specified multiple times.

       -u user
              Run the Sieve script for the given user. When omitted, the command will be executed
              with the environment of the currently logged in user.

       -x extensions
              Set the available extensions. The parameter is a space-separated list of the active
              extensions. By prepending the extension identifiers with + or -, extensions can  be
              included  or  excluded  relative  to the configured set of active extensions. If no
              extensions have a + or - prefix, only those extensions that are  explicitly  listed
              will be enabled. Unknown extensions are ignored and a warning is produced.

              For example -x "+imapflags -enotify" will enable the deprecated imapflags extension
              and disable the enotify extension. The rest of the active extensions depends on the
              sieve_extensions  and  sieve_global_extensions  settings.  By  default,  i.e.  when
              sieve_extensions and sieve_global_extensions  remain  unconfigured,  all  supported
              extensions  are available, except for deprecated extensions or those that are still
              under development.

ARGUMENTS

       sieve-binary
              Specifies the Sieve binary file that needs to be dumped.

       out-file
              Specifies where the output must be written. This argument is optional. If  omitted,
              the output is written to stdout.

EXIT STATUS

       sieve-dump will exit with one of the following values:

       0   Dump was successful. (EX_OK, EXIT_SUCCESS)

       1   Operation failed. This is returned for almost all failures.  (EXIT_FAILURE)

       64  Invalid parameter given. (EX_USAGE)

FILES

       /etc/dovecot/dovecot.conf
              Dovecot's main configuration file.

       /etc/dovecot/conf.d/90-sieve.conf
              Sieve interpreter settings (included from Dovecot's main configuration file)
