It seems that there is some keywords in the central cleaning house and I can’t update the blacklist… Maybe we should create a new one!

How to disable Outlook's level 1 attachment blocking feature

• Security

I’d say I really dislike this feature, it always prevent me from being able to receive attachments and does not actually block virii since I have some carefully designed security mechanisms installed on my computer.

Of course someone may say “Outlook sucks, don’t use it!” but I won’t say that. Outlook is a great product that is very safe if you have configured it *CORRECTLY*. The feature of the attachment blocking, while may be useful for not experienced users, will harm users that is experienced and is highly security-aware when communicating with non-experienced folks.

看了看ACM发来的spam专刊

• Security

感觉现在反垃圾技术发展到了一个坎上,短期内恐怕不会什么大的技术突破。基本的技术就是黑白名单、内容分析、特征分析。垃圾邮件发送的技术最近也没什么大的进展,目前我能够做到的漏判大约是万分之七,误判万分之五左右,前一阵考虑的技术还没有时间去做……

Fast jail vs qmail

• Security

It seems that the official FreeBSD qmail port’s disable-qmail (as well as the Live with Qmail documentation) will need write access to /usr/bin and /usr/libexec, and hence the “fast jail” script I have written has been rendered useless :-(

I will investigate the issue this weekend and hopefully I will be able to work around the issue.

Fighting against spamming

• Security

It seems that my blog get spammed by various parties. I hereby declare a war against spamming, also for e-mails.

You’re being watched and identified from this point on. Once you spam my blog, I guarantee that your activations are being tracked and analyzed with my knowledge base system and finally I will be able to keep everything from you off my site.

不按RFC走?那你必然会遇到麻烦

• Security

RFC也许有时让人觉得过分冗长,但是如果你没有耐心去完全实现它,它就会在不经意间突然咬你一口。

可怜的端木就被咬了……

今天这家伙发了一封邮件给我。

嗯?3.5分?

beastie.frontfree.net 活过来了

• Life

经历了更换硬盘打击之后的beastie总算活过来了(/var由于这次操作彻底消失了)。由于软件版本升级太多,考虑到综合成本,我部署了PhantasmMail 3.0-beta。目前尚需解决sasl的验证问题。
