False Spam are messages that are blank or contain garbled text with no links or real message.

Yes, they are unwanted messages but there is no real 'body' to the Spam - just some garbled words. The message that the Spammer wanted to send was not included and thus these messages are ineffective as Spam.

Why would the Spammers want to send 'False Spam'?

Just speculating here but it could be anything from someone doing a 'test spam run' that got away on them and sent nonsensical random text without the advertisement. If that is the case then 'Silly Spammer - you wasted your money on this one!'

It could also possibly be an effort to see what did get through by utilizing the 'Out of Office' or 'Delivery Receipts' to capture valid e-mail addresses. If the Spammer gets any response back except 'undeliverable' then they know that there is a valid e-mail address on the other side. It is a good idea to not send these 'Out of Office' messages outside your organization if at all possible. It is also a good idea to disable the 'Delivery or Read receipts' in both your e-mail client and your mail server as some people rely on them.

A third possibility is that Spammers may be trying to poison the Bayesian or statistical database by sending out these random words and phrases. A poisoned database will make it that much harder to pick the Spam out of the noise and could result in more false positives.

Rest assured that CudaMail is working hard to clean up these 'False Spam' messages as quickly as we can.
