NAME
ezmlm-weed - weed out useless messages

SYNOPSIS
ezmlm-weed

DESCRIPTION
ezmlm-weed reads a mail message from its standard input. If it recognizes the message as an MTA warning message or success message, or as a message with precedence ``bulk'' or ``junk'' as generated by vacation autoresponders, it exits 99; this will cause qmail-alias to skip all further delivery instructions if ezmlm-weed is run from a .qmail file. If the message seems innocent, ezmlm-weed exits 0. ezmlm-weed exits 111 if it runs out of memory.
