search to see if an IP is listed
e.g.: 209.134.156.193

 


I decided to publish via DNS this list of IP addresses I don't want to get
mail from.  That way I could export it easily to my multiple SMTP servers via zone
transfer or direct DNS lookup, and not have to maintain multiple access maps
manually or via something like rsync.

This RBL list is just one of many methods I use to manage incoming crud for my
inbox and the inboxes of my users.  My complete filtering solution includes things
like:

	this RBL list
	other public RBL lists
	stricter requirements on remote SMTP RFC compliance
	sender domain validation
	realtime sender address verification
	greylisting
	keyword rejection on incoming email body
	keyword rejection on incoming email header
	spamassassin
	clamav
	procmail rules
	MUA filtering/spam identification
	... and many other methods

I generally add /24 or /16 catch all entries when repeated spam comes from
a /24 or /16 and I don't foresee any legitimate email coming from these
hosts.

If you got a message telling you to come here because of a blocked email message,
be aware that one of two possibilities exists:

	1)  you tried to send email to a host I manage from an email server
	that I have decided not to communicate with.

	2) you tried to send email to a host which has decided to use my RBL list
	to block email.

You have no choice but to resend the email from a different host, one which is not
blocked.

Anyone can use this RBL list like any of the other major lists ( cbl.abuseat.org, etc )
by adding this to your MTA's RBL config ( DNSBL, NOT RHSBL!):

	rbl.schulte.org

With Postfix, for example, you can add this line where it's appropriate:

	reject_rbl_client rbl.schulte.org,

Feel free to drop me a line if you want to communicate anything to me about this list:

	postmaster@schulte.org
