It appears that some recent updates to Proofpoint, which many
organizations including Stanford use for scanning emails, has flagged
emails from CRAN as spam. A recent press release from Proofpoint
mentioning use of some AI agent doesn't exactly inspire confidence!
Our IT folks have opened a ticket with them and here's hoping that any
fix propagates up the chain.
(We struggled with this for over a week while submitting package updates
before stumbling on this silent menace.)
Just FYI.
