Usage: sieve [OPTION...] SCRIPT GNU sieve -- a mail filtering tool. -c, --compile-only compile script and exit -D, --dump compile script, dump disassembled sieve code to terminal and exit -d, --debug[=FLAGS] debug flags (defaults to "TPt") -E, --expression treat SCRIPT as Sieve program text -e, --email=ADDRESS override user email address --environment=NAME=VALUE set sieve environment value -f, --mbox-url=MBOX mailbox to sieve (defaults to user's mail spool) -k, --keep-going keep on going if execution fails on a message --line-info=BOOL print source location along with action logs (default) -n, --dry-run, --no-actions do not execute any actions, just print what would be done --no-program-name do not prefix diagnostic messages with the program name -t, --ticket=TICKET ticket file for user authentication -v, --verbose log all actions Global debugging settings --debug-level=LEVEL set Mailutils debugging level --debug-line-info show source info with debugging messages --log-facility=FACILITY output logs to syslog FACILITY -M, --mailer=MAILER use specified URL as the default mailer Sieve options --clear-include-path clear Sieve include path --clear-library-path, --clearpath clear Sieve library path -I, --includedir=DIR append DIR to the list of directories searched for include files -L, --libdir=DIR append DIR to the list of directories searched for library files --libdir-prefix=DIR add DIR to the beginning of the list of directories searched for library files Configuration handling --config-file=FILE load this configuration file; implies --no-config --config-lint check configuration file syntax and exit --config-verbose verbosely log parsing of the configuration files --no-config do not load site and user configuration files --no-site-config do not load site-wide configuration file --no-user-config do not load user configuration file --set=PARAM=VALUE set configuration parameter Informational options --config-help show configuration file summary --show-config-options show compilation options -?, --help give this help list --usage give a short usage message -V, --version print program version Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. Sieve-specific debug levels: trace1 - print parse tree before optimization trace2 - print parse tree after optimization trace3 - print parser traces trace4 - print tests and actions being executed trace9 - print each Sieve instruction being executed Compatibility debug flags: g - main parser traces T - mailutils traces (same as --debug-level=sieve.trace0-trace1) P - network protocols (same as --debug-level=sieve.=prot) t - sieve trace (same as --debug-level=sieve.=trace4) i - sieve instructions trace (same as --debug-level=sieve.=trace9) Report bugs to <bug-mailutils@gnu.org>.
