blq

Summary: 
query spam and email abuse block lists
Current release: 
1.23
Last updated: 
2002-11-12

Some organizations, such as the MAPS RBL and MAPS DUL, publish lists that identify potential sources of spam and email abuse. The blq utility is a Perl script that queries one or more of these lists to determine if a particular host is listed.

It works something like this ...

$ <strong>blq rbl,dul 127.0.0.2</strong>
127.0.0.2 : blackholes.mail-abuse.org : BLOCKED
127.0.0.2 : dialups.mail-abuse.org : ok
