NAME

6       sieve-dump - Pigeonhole's Sieve script binary dump tool
7

SYNOPSIS

9       sieve-dump [options] sieve-binary [out-file]
10

DESCRIPTION

12       The  sieve-dump  command  is  part  of  the Pigeonhole Project (pigeon‐
13       hole(7)), which adds Sieve (RFC 5228) support  to  the  Dovecot  secure
14       IMAP and POP3 server (dovecot(1)).
15
16       Using  the  sieve-dump  command, Sieve binaries, which are produced for
17       instance by sievec(1), can be transformed into a human-readable textual
18       representation.  This  can  provide  valuable  insight in how the Sieve
19       script is executed. This is also particularly useful  to  view  corrupt
20       binaries  that  can  result from bugs in the Sieve implementation. This
21       tool is intended mainly for development purposes,  so  normally  system
22       administrators and users will not need to use this tool.
23
24       The format of the output is not explained here in detail, but it should
25       be relatively easy to understand. The Sieve binaries comprise a set  of
26       data  blocks,  each  of  which can contain arbitrary data. For the base
27       language implementation two blocks are used:  the  first  containing  a
28       specification  of  all required language extensions and the second con‐
29       taining the main Sieve program. Compiled Sieve programs are represented
30       as  flat byte code and therefore the dump of the main program is a dis‐
31       assembly listing of the interpreter operations. Extensions  can  define
32       new  operations  and  use  additional  blocks. Therefore, the output of
33       sieve-dump depends greatly on the language extensions used when compil‐
34       ing the binary.

OPTIONS

37       -c config-file
38              Alternative Dovecot configuration file path.
39
40       -h     Produce  per-block hexdump output of the whole binary instead of
41              the normal human-readable output.
42
43       -x extensions
44              Set the available extensions. The parameter is a space-separated
45              list of the active extensions. By prepending the extension iden‐
46              tifiers with + or -, extensions can be included or excluded rel‐
47              ative  to the default set of extensions. If no extensions have a
48              + or - prefix, only those extensions that are explicitly  listed
49              will be enabled. Unknown extensions are ignored and a warning is
50              produced. By default, all supported  extensions  are  available,
51              except  for  deprecated extensions or those that are still under
52              development.
53
54              For example -x "+imapflags -enotify" will enable the  deprecated
55              imapflags extension along with all extensions that are available
56              by default, except for the enotify extension.

ARGUMENTS

59       sieve-binary
60              Specifies the Sieve binary file that needs to be dumped.
61
62       out-file
63              Specifies where the output must be  written.  This  argument  is
64              optional. If omitted, the output is written to stdout.
65

EXIT STATUS

67       sieve-dump will exit with one of the following values:
68
69       0   Delivery was successful. (EX_OK, EXIT_SUCCES)
70
71       1   Operation  failed.  This  is  returned  for  almost  all  failures.
72           (EXIT_FAILURE)
73
74       64  Invalid parameter given. (EX_USAGE)
75

FILES

77       /etc/dovecot/dovecot.conf
78              Dovecot's main configuration file.
79
80       /etc/dovecot/conf.d/90-sieve.conf
81              Sieve interpreter settings (included from Dovecot's main config‐
82              uration file)
83

REPORTING BUGS

85       Report  bugs, including doveconf -n output, to the Dovecot Mailing List
86       <dovecot@dovecot.org>.  Information about reporting Dovecot and Pigeon‐
