Here's the latest installment of this thrilling saga </irony>.
Apparently there's a spam-filtering service out there called ProofPoint. For some unknown reason, ProofPoint erroneously added the IP address of one of the servers of EMWD, the company that hosts our INDOLOGY service, to their blacklist. So I think that those of you who had INDOLOGY trouble in the last week or so may have been using email systems that in turn used ProofPoint (whether you knew it or not). Anyhow, EMWD wrote to ProofPoint and complained, and ProofPoint have unblocked the EMWD IP address. As I said (in vain) once before, things should be okay from now on.
