I have largely got spam now under control on my own mailserver at home using a combination of blocking lists, Razor2, Spamassison but about one email a day still slips through.
The spam I receive is all similar but completely different if that makes any sense.
It is all similar because every email is advertising some sort or pornographic link but never the same link.
The subject line is never the same but it always starts with some sort of obscene sentence but the last two or so words always make no sense in the context of the sentence. Here is an example (not an actual example obviously):
"She went to the shop to buy a pint of milk garden shed".
The emails come from all sorts of addresses, hotmail, yahoo, aol etc. but never the same address as I am continuously blacklisting addresses but the email keeps arriving from new addresses.
Spamassisan catches about 90% of it for various reasons, usually Razor2 but about one email a day has absolutely no spam score so will slip through.
I am convinced that this (at least started) as one spam database due to the similarities. Unfortunately, only a human can see the similarities so I am unable to use them to block 100% of it.
Has anyone else experienced this spam? Does anyone know of any further reading on this particular threat?
