The LDAP address book (LDAP = Lightweight Directory Access Protocol) is a type of database or directory that an email application queries via a predefined path (server name, port, branch/search base) in order to find out the user certificate of an email address, for example. If such an LDAP address book is integrated into your own email application, encrypted emails can be sent directly, for example, provided the recipients have published their user certificate in the LDAP address book. Not every e-mail has to be sent encrypted, but you can select this option if you wish and after successful setup. Read more about the encryption of emails in part 2 of the blog series.

On the other hand, every sender asks themselves at some point: How do I know whether my email has demonstrably reached the recipient unchanged? One answer to this is: Always sign emails digitally! We would like to take a closer look at this process with you in the following blog post.
