Site issue, 16 June 2018: Proofpoint Email Protection is intermittently refusing to deliver mail from HotCRP.com. Many sites contract with Proofpoint, including AT&T, IBM, University of Illinois, and Stanford University. HotCRP.com sends valid email, but Proofpoint uses “machine learning,” so this problem is likely to recur. We will work on a fix, but in the meantime Proofpoint customers, such as university IT departments, can manually whitelist mail.hotcrp.com’s IP address, 54.84.184.246, in Proofpoint’s so-called Dynamic Reputation service.
