[Mimedefang] OT but interesting hopefully - Spammers embrace email authentication

[Richard Cooper]

There's an interesting article on The Register regarding spammers making
use of SPF - I thought it might be of interest given recent discussions.
Sorry if anyone considers it too off-topic.

"More spam than legitimate email is currently sent using Sender Policy
Framework, a recently introduced email authentication protocol.
According to CipherTrust’s research, 34 per cent more spam is passing
SPF checks than legitimate email because spammers are actively
registering their SPF records."
