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.

       -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)
