qconfirm-check-mid(1)

NAME
qconfirm-check-mid - checks headers of a mail message for known references

SYNOPSIS
qconfirm-check-mid [-av] [ mid ... ]

DESCRIPTION
Normally qconfirm-check-mid is run by qconfirm-check(1) before requesting a delivery confirmation for mail from an envelope sender mail address. If qconfirm-check-mid exits 0, qconfirm-check(1) doesn't request a delivery confirmation from this sender.

qconfirm-check-mid assumes the environment variable SENDER to be set to the envelope sender mail address, and expects a mail message on standard input.

qconfirm-check-mid reads the headers of the message available on standard input, and checks for each ``In-Reply-To'' and ``References'' header if it contains a Message-ID that matches one of the space-separated mids in QCONFIRM_MID if set, or one of the mids given at the command line, and exits 0 if so.

A header is successfully matched against QCONFIRM_MID or mid if the header field contains the string ``mid>'', case distinctions are ignored. E.g., if qconfirm-check-mid is called

qconfirm-check-mid -a '@smarden.org'

this ``References'' header is matched successfully:

References: <20030326042405.32385.qmail@smarden.org> <some@thing>

OPTIONS

-a  accept. After successfully matching a header of the message, add the envelope sender of this message to the list of known ids before exiting, so that qconfirm-check(1) automatically accepts further messages from this sender.

-v  verbose. Print verbose messages to standard output.

CONFIGURATION
qconfirm-check-mid reads its configuration from files in the subdirectory conf/ of the qconfirm directory (normally ``~/.qconfirm/conf/''). Only the first line of a configuration file is considered.

QCONFIRM_MID
    The configuration file QCONFIRM_MID is optional, and may contain a space-separated list of mids.

ENVIRONMENT

SENDER
    qconfirm-check-mid assumes the environment variable SENDER to be set to the envelope sender mail address. If $SENDER is not set, qconfirm-check-mid complains and exits 100.

QCONFIRM_MID
    The environment variable QCONFIRM_MID is optional, and may contain a space-separated list of mids. The environment variable overrides the configuration file QCONFIRM_MID.

QCONFIRM_DIR
    The environment variable QCONFIRM_DIR overrides the default location of the user's qconfirm directory (``.qconfirm'').
