All dns that doesn't exist seems to resolve to the same IP Name: lkdsjfalkajsdfasf.net Address: 64.94.110.11
Name: qqqqqqqqqqqqqqqqqqqq.net Address: 64.94.110.11 Name: zzzzzzzzzzzzzzzzzzzzzzzzzz.net Address: 64.94.110.11 Wonder if we can blacklist where sender DNS = a specific IP -----Original Message----- From: Tom Baker|Netsmith Inc [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2003 7:34 PM To: '[EMAIL PROTECTED]' Subject: [IMGate] Re: One Less Tool? Open mouth insert foot. I spoke too fast. It appears as I still had some stuff cached as non-existent This is just coming online. GD bastards breaking DNS!

I thought that was still in the "Testing" phase? Also I thought I read where it wsa "supposed" to only return an A record for "www" requests and not otherwise effecting other services.... Now we all know that DNS doesn't know which protocol/service is needing the IP so that leaves me just HOPING that means they would only wildcard www.*.com and www.*.net and not *.com *.net I am still getting my unknown sender domain rejects just fine Sep 15 19:23:25 mx3 postfix/smtpd[78639]: 2EA1420275: reject: RCPT from adsl-67-116-199-234.dsl.sndg02.pacbell.net[67.116.199.234]: 554 <[EMAIL PROTECTED]>: Sender address rejected: Domain not found; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> proto=SMTP helo=<adsl-67-116-199-235.dsl.sndg02.pacbell.net> Sep 15 19:23:38 mx3 postfix/smtpd[78486]: E04302111D: reject: RCPT from fq.obmt.net[69.6.29.147]: 450 <[EMAIL PROTECTED]>: Sender address rejected: Domain not found; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> proto=ESMTP helo=<fq.obmt.net -----Original Message----- From: Chris Scott [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2003 7:13 PM To: [EMAIL PROTECTED] Subject: [IMGate] One Less Tool? With Verislime mucking upthe .net and .com DNS with wildcards, it looks like at least one of our spam fighting tools is gone: reject_unknown_sender_domain I just did a test from my RR connection: 220 mgw3.hostorlando.net ESMTP Postfix helo test.com 250 mgw3.hostorlando.net mail from:<[EMAIL PROTECTED]> 250 Ok rcpt to:<[EMAIL PROTECTED]> 554 Service unavailable; Client host [65.33.84.218] blocked using dynablock.easynet.nl; Dynamic/Residential IP range listed by easynet.nl DynaBlock - http://dynablock.easynet.nl/errors.html All my RBL checks are after reject_unknown_sender_domain which used to reject crap like this. -- Chris Scott Host Orlando, Inc. http://www.hostorlando.com/
