I'm wondering what the benefit of mirroring the SORBS lists for SmarterMail customers would entail --
I guess the real question is how big are the zone files. We personally don't do near the traffic on our service to require this - but I see some SM installs with thousands of users. Surely there might be some benefit to looking into this further. The DNS lookups could be restricted to SmarterMail servers via IP to protect against abuse or outside usage.
