sieve-test - Pigeonhole's Sieve script tester
sieve-test [options] script-file
mail-file
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.
- -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.
- 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.
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.
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.
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)
- /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)
