.SH NAME
sievec \- Pigeonhole\(aqs Sieve script compiler
.\"------------------------------------------------------------------------
.SH SYNOPSIS
.B sievec
.RI [ options ]
.I script\-file
.RI [ out\-file ]
.\"------------------------------------------------------------------------
.SH DESCRIPTION
.PP
The \fBsievec\fP command is part of the Pigeonhole Project
(\fBpigeonhole\fR(7)), which adds Sieve (RFC 5228) support to the Dovecot
secure IMAP and POP3 server (\fBdovecot\fR(1)).
.PP
Using the \fBsievec\fP command, Sieve scripts can be compiled into a binary
representation. The resulting binary can be used directly to process e\-mail
messages during the delivery process. The delivery of mail messages and \- by
means of the LDA Sieve plugin \- also the execution of Sieve scripts is
performed by Dovecot\(aqs local delivery agent (LDA) called \fBdovecot\-lda\fP(1).
Usually, it is not necessary to compile the Sieve script manually using
\fBsievec\fP, because \fBdovecot\-lda\fP will do this automatically if the binary
is missing. However, in some cases \fBdovecot\-lda\fP does not have permission to
write the compiled binary to disk, forcing it to recompile the script every time
it is executed. Using the \fBsievec\fP tool, this can be performed manually by
an authorized user to increase performance.
.PP
The Pigeonhole Sieve implementation recognizes files with a \fB.sieve\fP
extension as Sieve scripts and corresponding files with a \fB.svbin\fP extension
as the associated compiled binary. This means for example that Dovecot\(aqs LDA
process will first look for a binary file \(dqdovecot.svbin\(dq when it needs to
execute \(dqdovecot.sieve\(dq. It will compile a new binary when it is missing
or outdated.
.PP
The \fBsievec\fP command is also useful to verify Sieve scripts before using.
Additionally, with the \fB\-d\fP option it can output a textual (and thus
human\-readable) dump of the generated Sieve code to the specified file. The
output is then identical to what the \fBsieve\-dump\fP(1) command produces for a
stored binary file. This output is mainly useful to find bugs in the compiler
that yield corrupt binaries.
.\"------------------------------------------------------------------------
.SH OPTIONS
.TP
.BI \-c\  config\-file
Alternative Dovecot configuration file path.
.TP
.B \-d
Don\(aqt write the binary to \fIout\-file\fP, but write a textual dump of the
binary instead. In this context, the \fIout\-file\fP value '\-' has special
meaning: it causes the the textual dump to be written to \fBstdout\fP.
The \fIout\-file\fP argument may also be omitted, which has the same effect
as '\-'.
The output is identical to what the \fBsieve\-dump\fP(1) command produces
for a compiled Sieve binary file. Note that this option is not allowed when the
\fIout\-file\fP argument is a directory.
.TP
.B \-D
Enable Sieve debugging.
.TP
.BI \-o\  setting = value
Overrides the configuration
.I setting
from
.I /etc/dovecot/dovecot.conf
and from the userdb with the given
.IR value .
In order to override multiple settings, the
.B \-o
option may be specified multiple times.
.TP
.BI \-u\  user
Run the Sieve script for the given \fIuser\fP. When omitted, the
.I command
will be executed with the environment of the currently logged in user.
.TP
.BI \-x\  extensions
Set the available extensions. The parameter is a space\-separated list of the
active extensions. By prepending the extension identifiers with \fB+\fP or
\fB\-\fP, extensions can be included or excluded relative to the configured set
of active extensions. If no extensions have a \fB+\fP or \fB\-\fP prefix, only
those extensions that are explicitly listed will be enabled. Unknown extensions
are ignored and a warning is produced.

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

.\"------------------------------------------------------------------------
.SH ARGUMENTS
.TP
.I script\-file
Specifies the script to be compiled. If the \fIscript\-file\fP argument is a
directory, all files in that directory with a \fI.sieve\fP extension are
compiled into a corresponding \fI.svbin\fP binary file. The compilation is not
halted upon errors; it attempts to compile as many scripts in the directory as
possible. Note that the \fB\-d\fP option and the \fIout\-file\fP argument are
not allowed when the \fIscript\-file\fP argument is a directory.
.TP
.I out\-file
Specifies where the (binary) output is to be written. This argument is optional.
If this argument is omitted, a binary compiled from <scriptname>.sieve is saved
as <scriptname>.svbin. If this argument is omitted and \fB\-b\fP is specified,
the binary dump is output to \fBstdout\fP.
.\"------------------------------------------------------------------------
.SH "EXIT STATUS"
.B sievec
will exit with one of the following values:
.TP 4
.B 0
Compile was successful. (EX_OK, EXIT_SUCCESS)
.TP
.B 1
Operation failed. This is returned for almost all failures.
(EXIT_FAILURE)
.TP
.B 64
Invalid parameter given. (EX_USAGE)
.\"------------------------------------------------------------------------
.SH FILES
.TP
.I /etc/dovecot/dovecot.conf
Dovecot\(aqs main configuration file.
.TP
.I /etc/dovecot/conf.d/90\-sieve.conf
Sieve interpreter settings (included from Dovecot\(aqs main configuration file)
