Spam filter using relays.osirusoft.com

Testing IP address

You can use ping for testing. For example, for IP a.b.c.d type

ping d.c.b.a.relays.osirusoft.com.

Don’t forget the ending dot.

If this returns BAD/UNKNOWN IP, then it’s ok. If it returns a 127.0.0.x number, then this means something:

Testing results

127.0.0.2	Verified Open Relay. A verified open relay in most cases is handled by other relay blocklist servers, and imported into the Zone file.
127.0.0.3	Dialup Spam Source. Dialup Spam Sources are imported into the Zone file from other sources and some known sources are manually added to the local include file.
127.0.0.4	Confirmed Spam Source. A site has been identified as a constant source of spam, and is manually added. Submissions for this type of spam require multiple nominations from multiple sites.
127.0.0.5	Smart Host (In progress). A Smart host is a site determined to be secure, but relays for those who are not, defeating one level of security. When this is ready, it will be labeled outputs.osirusoft.com. NOTE: I strongly discourage using outputs due to it being way too effective to be useful.
127.0.0.6	A Spamware software developer or spamvertized site.  This information will automatically be maintained by www.spamsites.org shortly.
127.0.0.7	A list server that automatically opts users in without confirmation
127.0.0.8	An insecure formmail.cgi script. (Planned)
127.0.0.9	Open proxy servers

Testing it with a batch file (Windows NT)

@echo off if "%1" == "" goto :help for /f "tokens=1,2,3,4* delims=." %%i in ("%1") do call :test %%i %%j %%k %%l rem use this to read a list file with ip addresses rem for /f "tokens=1,2,3,4* delims=." %%i in (%1) do call :test %%i %%j %%k %%l goto :eof :test ping %4.%3.%2.%1.relays.osirusoft.com. goto :eof :help echo syntax: testspam ip_address goto :eof

Example:

testspam 1.223.233.203..relays.osirusoft.com.

The NT batch trick above parses the line passed by ("%1") if you change this to a file name (without quotes), then it will read each line in the file.
