Only a limited number of messages is allowed to enter the active queue (leaky bucket strategy, for a fixed delivery rate). =item deferred Mail that could not be delivered upon the first attempt. The queue manager implements exponential backoff by doubling the time between delivery attempts. =item corrupt Unreadable or damaged queue files are moved here for inspection. =back =head1 CONFIGURATION By default "postconf -h queue_directory" is used to determine the spool directory. If postconf is not available in the $PATH then /var/spool/postfix is assumed. This can be overridden by the "spooldir" environment variable like so: [postfix_mailqueue] env.spooldir /var/spool/postfix =head1 AUTHOR Unknown. =head1 LICENSE Unknown. =head1 MAGIC MARKERS =begin comment These magic markers are used by munin-node-configure when installing munin-node. =end comment #%# family=auto #%# capabilities=autoconf =cut # Attempt to get spooldir via postconf, but environment overrides. # Remember that postconf is not available unless postfix is. if [ -n "${spooldir}" ]; then SPOOLDIR=${spooldir} else SPOOLDIR="$(postconf -h queue_directory 2>/dev/null || echo /var/spool/postfix)" fi .
