# This is a snmptrapd handler script to convert snmp traps into email
# messages.
# Usage:
# Put a line like the following in your snmptrapd.conf file:
# traphandle TRAPOID|default /usr/local/bin/traptoemail [-f FROM] [-s SMTPSERVER]b ADDRESSES
# FROM defaults to "root"
# SMTPSERVER defaults to "localhost"

designed to be called as an snmptrapd extension via a \"traphandle\"
directive in the snmptrapd.conf file. See the snmptrapd.conf file for
