Courtesy of Merlin Mann’s de.licio.us tags, I found out about SPF, Sender Policy Framework. Merlin had earlier apologized to the readers of his blog that he was not the sender of spam coming from the 43folders.com domain.

On my home Linux Box (Whitebox Enterprise 3.0) I use a number of different users for various purposes. I tend to create and delete them fairly often.
I suddenly started seeing a warning when creating or deleting a user:
