rlytest

Summary: 
test mail host for third-party relay
Current release: 
1.22
Last updated: 
2001-10-21

The rlytest utility tests a host to determine whether it will relay third-party email. It will try to relay an email message to yourself through that host. A host that allows third-party relay is subject to attack by Internet vandals, and frequently is hijacked by spammers to relay massive amounts of junk email. A host that allows third-party relay should be immediately secured, disconnected, or shunned as a menace to the Internet.

pxytest

Summary: 
test for open proxy server that allows mail relay
Current release: 
1.36
Last updated:

pxytest is a command line utility to test a host for open proxies that are vulnerable to spammer abuse. It is written in perl.

Unsecured proxies can be a conduit of spam. This is a particularly vexing problem, because open proxies, unlike open mail relays, hide the origin of the spam, making it impossible to trace. This utility
tests a host to see if it is vulnerable to such abuse.

blq

Summary: 
query spam and email abuse block lists
Current release: 
1.23
Last updated:

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
