Version 0.0.1
SYNOPSIS
rbl_mail|perl:rbl -H 192.0.2.25 -s zen.spamhaus.org -s bl.spamcop.net
rbl_mx|perl:rbl -H mail.example.org -s zen.spamhaus.org -w 0 -c 1DESCRIPTION
Looks each address of a host up on each block list given, through Net::DNS, with Net::IP for the reversed address. A hostname is looked up for its A and AAAA records first.
A listing is a A record for it. The number of listings is checked against the ranges, so by default any is CRITICAL. A lookup that gets no usable reply, such as none at all or SERVFAIL, is UNKNOWN, unless the listings are worse.
OPTIONS
- -H, --hostname :: The IP or host. Required.
- -s, --rbl :: A block list zone, such as zen.spamhaus.org. May be given more than once. Required.
- --server :: A DNS server to ask. May be given more than once. The system's if not given.
- -w, --warning :: Range for the number of listings.
- -c, --critical :: Range for the number of listings. Default :: 0
