Forum Suggestions & User Assistance - bikeforums.net blacklisted by ix.dnsbl.manitu.net for spamming

Hi. I'd like to get in touch with the administrator of BikeForums.net to notify them of the blacklist. The error message is:


Aug 13 04:31:36 server1 postfix/smtpd[4077]: NOQUEUE: reject: RCPT from mx5.internetbrands.com[98.158.194.50]: 554 5.7.1 Service unavailable; Client host [98.158.194.50] blocked using ix.dnsbl.manitu.net; Your e-mail service was detected by mail.ixlab.de (NiX Spam) as spamming at Mon, 13 Aug 2012 07:44:13 +0200. Your admin should visit http://www.dnsbl.manitu.net/lookup.php?value=98.158.194.50; from=<...[at]bikeforums.net> to=<...> proto=ESMTP helo=<mx5.internetbrands.com>

Right now, I have "reject_rbl_client ix.dnsbl.manitu.net" commented out in the "smtpd_recipient_restrictions" section. I'm using Postfix. Hopefully, e-mail from bikeforums.net should go through.

I have notified Tom Stormcrowe about this. Moving the thread to User Assistance.

I could have looked at the User Assistance forum. Thanks.

We don't send out spam, and only email people who register for the forums. You'll beed to whitelist the domain (at)bikeforums(dot)net, though.

Ah, thanks. I'll need to figure out how I can whitelist bikeforums.net in Postfix.

This is what I have so far:

I'm so glad I don't manage a postfix server anymore.

My curiosity is how bikeforums.net got blacklisted in the first place.

Thanks. I'm unsure if I could add user1@domainA.com and user2@domainB.com to rbl_override, but time will tell if it works.

Maybe the same IP address have been used previously before BikeForums.net took over the IP address.

I've had a feeling that we are running out of IP addresses. Why haven't we gradually switched over to IPv6 yet? I don't think I've gotten an IPv6 from FairPoint Communications where my mom ordered the service from.

At least I can receive e-mails coming from BikeForums.net, thanks to bypassing blacklist checks.
