论文摘要
本文根据简单邮件传输协议（SMTP）的修改提供了一种新颖的活动黑名单（ABL）。 ABL是在电子邮件服务器Zimbra的邮件传输代理（MTA）后缀中实现的，并在一系列实验中进行了详尽的评估。修改后的服务器Zimbra显示了计算性能，并且在接收合法电子邮件时与原始服务器Zimbra的成本相似。但是，在接收垃圾邮件时，它显示出比原始Zimbra更好的计算性能和成本。此外，当垃圾邮件发送垃圾邮件发送电子邮件时，垃圾邮件发送者的服务器上的计算成本很大。在六十一天的时间里，在巴西的联邦大学对ABL进行了评估。它负责拒绝大学在此期间收到的垃圾邮件电子邮件中20.94％的百分比。在此期间，从2015年7月至2019年7月至2019年7月在大学，它被部署并保留。 ABL是新的基于开放的机器学习的反垃圾邮件（开放式马巴斯）的一部分。 ABL和开放式马巴斯都可以在GitHub上免费获得。
This paper presents a novel Active Blacklist (ABL) based on a modification of the Simple Mail Transfer Protocol (SMTP). ABL was implemented in the Mail Transfer Agent (MTA) Postfix of the e-mail server Zimbra and assessed exhaustively in a series of experiments. The modified server Zimbra showed computational performance and costs similar to those of the original server Zimbra when receiving legitimate e-mails. When receiving spam, however, it showed better computing performance and costs than the original Zimbra. Moreover, there was a considerable computational cost on the spammer's server when it sent spam e-mails. ABL was assessed at the Federal University of Itajubá, Brazil, during a period of sixty-one days. It was responsible for rejecting a percentage of 20.94% of the spam e-mails received by the university during this period. After this period, it was deployed and remained in use, from July-2015 to July-2019, at the university. ABL is part of the new Open Machine-Learning-Based Anti-Spam (Open-MaLBAS). Both ABL and Open-MaLBAS are freely available on GitHub.
