       sievec - Pigeonhole's Sieve script compiler


       sievec [options] script-file [out-file]


       The  sievec  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  sievec 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's local delivery agent (LDA)
       called dovecot-lda(1).  Usually, it is not  necessary  to  compile  the
       Sieve  script  manually  using sievec, because dovecot-lda will do this
       automatically  if  the  binary  is  missing.  However,  in  some  cases
       dovecot-lda  does  not  have permission to write the compiled binary to
       disk, forcing it to recompile the script every  time  it  is  executed.
       Using  the sievec tool, this can be performed manually by an authorized
       user to increase performance.

       The Pigeonhole Sieve implementation  recognizes  files  with  a  .sieve
       extension  as  Sieve  scripts  and  corresponding  files  with a .svbin
       extension as the associated compiled binary.  This  means  for  example
       that   Dovecot's  LDA  process  will  first  look  for  a  binary  file
       "dovecot.svbin" when it  needs  to  execute  "dovecot.sieve".  It  will
       compile a new binary when it is missing or outdated.

       The sievec command is also useful to verify Sieve scripts before using.
       Additionally, with the -d 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 sieve-dump(1) command produces
       for  a stored binary file. This output is mainly useful to find bugs in
       the compiler that yield corrupt binaries.


       -c config-file
              Alternative Dovecot configuration file path.

       -d     Don't write the binary to out-file, but write a textual dump  of
              the  binary instead. In this context, the out-file value '-' has
              special meaning: it causes the the textual dump to be written to
              stdout.   The  out-file  argument may also be omitted, which has
              the same effect as '-'.  The output is  identical  to  what  the
              sieve-dump(1) command produces for a compiled Sieve binary file.
              Note that this option is not allowed when the out-file  argument
              is a directory.

       -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 default set of 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.  By default, all supported extensions are
              available, except for deprecated extensions or  those  that  are
              still under development.

              For  example -x "+imapflags -enotify" will enable the deprecated
              imapflags extension along with all extensions that are available
              by default, except for the enotify extension.


              Specifies the script to be compiled. If the script-file argument
              is a directory, all  files  in  that  directory  with  a  .sieve
              extension  are compiled into a corresponding .svbin binary file.
              The compilation is  not  halted  upon  errors;  it  attempts  to
              compile  as many scripts in the directory as possible. Note that
              the -d option and the out-file argument are not allowed when the
              script-file argument is a directory.

              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 -b is specified, the binary dump
              is output to stdout.


       sievec will exit with one of the following values:

       0   Compile was successful. (EX_OK, EXIT_SUCCESS)

       1   Operation  failed.  This  is  returned  for  almost  all  failures.

       64  Invalid parameter given. (EX_USAGE)
