Is there a RHSBL for parked domains?
My users make a lot of typos in their recipient email addresses. Is there an easy way (i.e. a RHSBL) for parked domains? Or is there another easy way of detecting parked domains? Things that come to mind: * hostname resolve to but a few IP addresses * NS records for domain point to special parking DNS servers * other stuff Victor has found out, but I haven't -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de

You might be able to do something with check_recipient_mx_access.
Search around and see if you can find a list of parking IPs
somewhere. And then tell us about it, and look really smart.
But this probably won't help with the typical squatter or
{defensively owned by the real} domain... probably stuck with
whack-a-mole there.

Zitat von Ralf Hildebrandt ralf.hildebra...@charite.de: My users make a lot of typos in their recipient email addresses. Is there an easy way (i.e. a RHSBL) for parked domains? Get your users to use a managed address book so they don't have to type the address. Seriously this was the only way we got down the number of misrouted mails. You can't imaging how creative humans are in mistyping. Regards Andreas smime.p7s Description: S/MIME Cryptographic Signature

In my case my users keep hitting parked domains
