Apr 23, 2008 Have you been inundated with “undeliverable” emails?

Starting this past Monday night and running into yesterday morning, I got flooded with a few hundred e-mails — many from Russia and elsewhere overseas, and many with attachments that I did not open — proclaiming that e-mails I never sent were undeliverable. I tried setting my webhost’s filtering software to reject emails with such titles as undeliverable, postmaster and daemon. Whether or not it was coincidental, the flood reduced to a steady stream and then a trickle.

Did any of you experience the same thing? If so, how did you resolve the problem? A colleague who uses the same sitehost as ours told me it happened to him, and that his spam filtering software had to play catch-up to start filtering out such spam e-mail. (For some light diversion, see Monty Python’s Spam sketch that gave birth to computer spaminology.)

Thanks to our sitehost for sending me the following message describing this flood of spam: "I just added an SPF record https://en.wikipedia.org/wiki/Sender_Policy_Framework. It should help. This is a byproduct of spammers called backscattering https://en.wikipedia.org/wiki/Backscatter."

Spam is a thorny cost of my insistence that spamming be strongly protected by the First Amendment. Jon Katz.
