Setup
Our main physical server is located in a data center in The Netherlands and is owned by User:Lennart. Its address is nl1.dlnet.org
.
The server runs Linux Containers. Each user has a container with a full Debian installation. The user containers only have an IPv6 address, unless they pay for an IPv4 address. Therefore, all services (HTTP, SMTP and IMAP) are proxied via the container mail.dlnet.org
.
mail.dlnet.org
also does spam checking for incoming mail and is responsible for HTTPS encryption. Its outgoing email is routed via Amazon Web Services. This is necessary, at the moment, because large email providers like Google have a tendency to mark emails as spam that come from servers with low sending volumes.
backup.dlnet.org
is a dedicated server hosted by OVH (France). Its only purpose is to temporarily store incoming email when nl1.dlnet.org
is down.
