NAME

       sieve-test - Pigeonhole's Sieve script tester

SYNOPSIS

       sieve-test [options] script-file mail-file

DESCRIPTION

       The sieve-test 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-test command, the execution of Sieve scripts can be tested. This evaluates
       the script for the provided message, yielding a set of Sieve actions. Unless the -e option
       is specified, it does not actually execute these actions, meaning that it does  not  store
       or  forward  the message anywere. Instead, it prints a detailed list of what actions would
       normally take place.  Note  that,  even  when  -e  is  specified,  no  messages  are  ever
       transmitted  to remote SMTP recipients. The outgoing messages are always printed to stdout
       instead.

       This is a very useful tool to debug the execution of Sieve scripts.  It  can  be  used  to
       verify newly installed scripts for the intended behaviour and it can provide more detailed
       information about script execution problems that are reported by  the  Sieve  plugin,  for
       example by tracing the execution and evaluation of commands and tests respectively.

OPTIONS

-a orig-recipient-address
The original envelope recipient address. This is what Sieve's envelope test will
compare to when the "to" envelope part is requested. Some tests and actions will
also use this as the script owner's e-mail address. If this option is omitted, the
recipient address is retrieved from the "Envelope-To:", or "To:" message headers.
If none of these headers is present either, the recipient address defaults to
recipient@example.com.

-c config-file
Alternative Dovecot configuration file path.

-C Force compilation. By default, the compiled binary is stored on disk. When this
binary is found during the next execution of sieve-test and its modification time
is more recent than the script file, it is used and the script is not compiled
again. This option forces the script to be compiled, thus ignoring any present
binary. Refer to sievec(1) for more information about Sieve compilation.

-D Enable Sieve debugging.

-d dump-file
Causes a dump of the generated code to be written to the specified file. This is
identical to the dump produced by sieve-dump(1). Using '-' as filename causes the
dump to be written to stdout.

-e Enables true execution of the set of actions that results from running the script.
In combination with the -l parameter, the actual delivery of messages can be
tested. Note that this will not transmit any messages to remote SMTP recipients.
Such actions only print the outgoing message to stdout.

-f envelope-sender
The envelope sender address (return path). This is what Sieve's envelope test will
compare to when the "from" envelope part is requested. Also, this is where response
messages are 'sent' to. If this option is omitted, the sender address is retrieved
from the "Return-Path:", "Sender:" or "From:" message headers. If none of these
headers is present either, the sender envelope address defaults to
sender@example.com.

-l mail-location
The location of the user's mail store. The syntax of this option's mail-location
parameter is identical to what is used for the mail_location setting in the Dovecot
config file. This parameter is typically used in combination with -e to test the
actual delivery of messages. If -l is omitted when -e is specified, mail store
actions like fileinto and keep are skipped.

-m default-mailbox
The mailbox where the keep action stores the message. This is "INBOX" by default.

-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.

-r recipient-address
The final envelope recipient address. Some tests and actions will use this as the
script owner's e-mail address. For example, this is what is used by the vacation
action to check whether a reply is appropriate. If the -r option is omitted, the
original envelope recipient address will be used instead (see -a option for more
info).

-s script-file
Specify additional scripts to be executed before the main script. Multiple -s
arguments are allowed and the specified scripts are executed sequentially in the
order specified at the command line.

-t trace-file
Enables runtime trace debugging. Trace debugging provides detailed insight in the
operations performed by the Sieve script. Refer to the runtime trace debugging
section below. The trace information is written to the specified file. Using '-'
as filename causes the trace data to be written to stdout.

-T trace-option
Configures runtime trace debugging, which is enabled with the -t option. Refer to
the runtime trace debugging section below.

-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

       script-file
              Specifies the script to (compile and) execute.

              Note that this tool looks for a pre-compiled binary file with  a  .svbin  extension
              and  with basename and path identical to the specified script. Use the -C option to
              disable this behavior by forcing the script to be compiled into a new binary.

       mail-file
              Specifies the file containing the e-mail message to test with.

USAGE

RUNTIME TRACE DEBUGGING
Using the -t option, the sieve-test tool can be configured to print detailed trace
information on the Sieve script execution to a file or standard output. For example, the
encountered commands, the performed tests and the matched values can be printed.

The runtime trace can be configured using the -T option, which can be specified multiple
times. It can be used as follows:

-Tlevel=...
Set the detail level of the trace debugging. One of the following values can be
supplied:

actions (default)
Only print executed action commands, like keep, fileinto, reject and redirect.

commands
Print any executed command, excluding test commands.

tests
Print all executed commands and performed tests.

matching
Print all executed commands, performed tests and the values matched in those tests.

-Tdebug
Print debug messages as well. This is usually only useful for developers and is likely
to produce messy output.

-Taddresses
Print byte code addresses for the current trace output. Normally, only the current Sieve
source code position (line number) is printed. The byte code addresses are equal to
those listed in a binary dump produced using the -d option or by the sieve-dump(1)
command.

DEBUG SIEVE EXTENSION
To improve script debugging, this Sieve implementation supports a custom Sieve language
extension called 'vnd.dovecot.debug'. It adds the debug_log command that allows logging
debug messages.

Example:

require "vnd.dovecot.debug";

if header :contains "subject" "hello" {

debug_log "Subject header contains hello!";

}

Tools such as sieve-test, sievec and sieve-dump have support for the vnd.dovecot.debug
extension enabled by default and it is not necessary to enable nor possible to disable the
availability of the debug extension with the -x option. The logged messages are written to
stdout in this case.

In contrast, for the actual Sieve plugin for the Dovecot LDA (dovecot-lda(1)) the
vnd.dovecot.debug extension needs to be enabled explicitly using the sieve_extensions
setting. The messages are then logged to the user's private script log file. If used in a
global script, the messages are logged through the default Dovecot logging facility.

EXIT STATUS

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

       0   Execution 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)
