Slashdot 的 People are More Accepting of Spam 提到了：雖然信箱裡的 Mail Spam 愈來愈多，但他們愈來愈不在乎這點。

在原來的新聞 Spam and phishing 裡面提到：

More than a year after the CAN-SPAM Act became law, email users say they are receiving slightly more spam in their inboxes than before, but they are minding it less.

另外一點值得注意的是，收到 Porn Spam 的情況愈來愈少：

Among other things, the survey found that people were getting less porn spam, a uniquely troubling form of spam for most users and particularly for women. While 63% of email users now say they have received porn spam, down 8 percentage points from a year ago, 29% of those email users say they are now getting less porn spam, compared to 16% who said they are getting more.

在還沒開 Greylisting 以前，收到的 spam 數量大約在 300 spam/day 封左右，目前打開後剩下 50 spam/day，其中大部分都被 DSpam 給丟到 Spam Folder 了。

目前有一些新的技術在跑，像是 Yahoo! 在推的 DomainKeys、Microsoft 與 Pobox 在推的 Sender Policy Framework (雖然我覺得這是一個問題很多的技術)，但突破的方法其實也都有，而且都不難。

只要透過 Open Proxy 用 Provider 的 Webmail 硬送就可以了。如果遇到 AuthImage 類 () 的方式，我猜測這些 Spam Software 的發展者會直接把國外論文的成果 import 進去，有九成左右的辨識率。
