Intelligent greylisting with NoSpamProxy

Every day, millions of unwanted emails are sent over the internet. Spam filters do their best to block these emails, but some unwanted messages still find their way into our inboxes. There is a frequently overlooked but effective protective measure against spam: greylisting. The principle behind greylisting is to save time. With greylisting, emails are initially rejected and only accepted after a second delivery attempt. In addition, greylisting separates legitimate mail servers from those that do not comply with the relevant RFCs.

In this article, you will learn how greylisting works, why it is still an integral part of modern spam protection today, and why the intelligent greylisting in NoSpamProxy is particularly effective.

Using the Electronic Court and Administration Mailbox (EGVP) with NoSpamProxy

Digitization has also led to fundamental changes in the legal and administrative sectors. One of the most important developments was the introduction of the Electronic Court and Administration Mailbox (EGVP), which enabled the secure exchange of documents between citizens, companies, lawyers, authorities, and courts. The EGVP has since been replaced by specialized electronic mailboxes such as beA, beN, beBPo, beSt, and eBO—each with a clearly defined scope of application. The following overview shows the development from the original EGVP to today’s solutions and explains how they work in practice.
