I have been detecting a trend that attacks on email servers. Or rather email spams by automated software is getting more and more. What's worse it seems to be from smtp servers all over the world. Not just open relays, maybe vulnerable relays, respectable providers etc whose clients may be careless. These emails cant be blocked as they are distributed. The RBL I am using wont be updating a lot of them as the smtp may be temporary victims of viruses etc. Finding it very difficult to prevent such spams from all over the place, similar scenario to DDOS attacks : (. Anyway to prevent?
Is spam really that effective that so many people still continue using it? I really wonder? My side, I am getting to the stage that if I am not a hosting provider, I would just stop using email altogether. A phone SMS etc seems better. At least SMS cost much more than emails, I still dun expect that great amount of SMS spams compared to email spams.
Really hope spammers realise the way they are doing, they are killing the goose that lay the golden eggs.
