qconfirm-cdb-check(1)qconfirm-cdb-check(1)NAMEqconfirm-cdb-check - match a mail address against a constant database
SYNOPSISqconfirm-cdb-check [-vD] [-c cdb] [-t sec]
DESCRIPTION
Normally qconfirm-cdb-check is run by qconfirm-check(1) before request‐
ing a delivery confirmation for mail from an envelope sender mail
address. If qconfirm-cdb-check exits 0, qconfirm-check(1) doesn't
request a delivery confirmation from this sender.
qconfirm-cdb-check assumes the environment variable SENDER to be set to
the envelope sender mail address. It creates an id based on $SENDER,
and matches the id against entries in the constant database ~/.qcon‐
firm/ok.cdb. ok.cdb normally is created and maintained by qconfirm-
cdb-update(1).
If qconfirm-cdb-check successfully matches $SENDER, it reads the time-
stamp of the id that matches $SENDER in ok.cdb, updates the time-stamp
if it is older than sec seconds, and exits 0.
OPTIONS-c cdb Set the filename of the constant database to be checked to cdb.
Default is ``ok.cdb'' (in the qconfirm directory). This option
also overrides the environment variable QCONFIRM_OKCDB, and the
configuration file QCONFIRM_OKCDB. Note: If qconfirm-cdb-check
updates cdb, it creates cdb.tmp as temporary file. If cdb.tmp
exists, it will be destroyed.
-t sec Set the interval for updating time-stamps of ids in cdb to sec
seconds. Default is 2419200 (four weeks).
-D no domain match. Don't use extended envelope sender addresses
matching for domains and sub-domains.
-v verbose. Print verbose messages to standard output.
CONFIGURATIONqconfirm-cdb-check reads its configuration from files in the subdirec‐
tory conf/ of the qconfirm directory (normally ``~/.qconfirm/conf/'').
Only the first line of a configuration file is considered.
QCONFIRM_OKCDB
The configuration file QCONFIRM_OKCDB overrides the default name
of the user's constant database for known ids (``ok.cdb'').
ENVIRONMENT
SENDER qconfirm-cdb-check assumes the environment variable SENDER to be
set to the envelope sender mail address. If $SENDER is not set,
qconfirm-cdb-check complains and exits 100.
QCONFIRM_DIR
The environment variable QCONFIRM_DIR overrides the default
location of the user's qconfirm directory (``.qconfirm'').
QCONFIRM_OKCDB
The environment variable QCONFIRM_OKCDB overrides the default
name of the user's constant database for known ids (``ok.cdb''),
and the configuration file QCONFIRM_OKCDB.
