If you have registered your domains with another provider, you can move them to dotplex. This has the advantage that we can make all necessary DNS settings directly for you and also offer you the DNSSEC security mechanism. If a transfer is not an option, you can find here how to configure your external domain manually for dotplex.

Method 1: Using the dotplex name servers

Even if you do not want to move your domain to dotplex, you are welcome to use our name servers. This has the advantage that we can make all DNS settings correctly for you. However, we do not offer the activation of DNSSEC for external domains, as this would require regular manual updates of the signature keys at your registrar.

To use the dotplex name servers, please let us know the domain name so that we can configure the domain on our servers. Afterwards you can configure the two dotplex name servers with your registrar:

  • ns.dotplex.net
  • ns2.dotplex.de

Method 2: Using your own name servers

You are also welcome to use your own name servers or those of your registrar. This is particularly useful if you only want to use individual services at dotplex with this domain, e.g. only email or only a website at a sub-domain. If DNSSEC is supported by your registrar and name server operator, you should activate it.

Configure the following settings with your DNS provider:

DNS records for web servers

To redirect your domain or a sub-domain to your web server or hosting account at dotplex, configure the following settings. If you only want to use the domain at dotplex for email and your website is hosted by another provider, skip this step.

For the www sub-domain (or another sub-domain), create a CNAME record to the dotplex server where your website is located. You can find the server name (e.g. web1.dotplex.com) in your account in the web configuration, in the confirmation mail for ordering your server or you simply ask us again.

If you also want to redirect your root domain (e.g. example.org) to the website, this is not possible via a CNAME entry. Therefore you should set up a redirect of the root domain to the subdomain www (in the example www.example.org) with your DNS provider.

Example of the CNAME record to be entered:

Sub-domain Type Value
www CNAME web1.dotplex.com.

DNS records for mail servers

To forward incoming mails to the dotplex mail servers, configure the following settings at your DNS provider. If you only want to host your website at dotplex, but your mails are hosted with another provider, skip this step.

MX

Create an MX record with priority 10. Remove any other MX records that may exist:

Sub-domain Type Priority Value
MX 10 mx.dotplex.com.

SPF

Optionally create an SPF record. This allows you to specify which mail servers are allowed to send emails from your domain and reduces the probability that your mails are classified as spam by the recipient.

If all emails for the domain are sent exclusively via dotplex, the SPF record is:

Sub-domain Type Value
TXT v=spf1 include:_spf.dotplex.com ~all

If you also send emails from this domain via other mail servers (e.g. newsletter tools), ask them for the necessary adjustments to your SPF entry.

DKIM

Optionally create two CNAME entries for DKIM. Our mail servers automatically sign outgoing emails with DKIM. The recipients' mail servers need these DNS entries to be able to verify the signature. This also reduces the spam probability of your mails.

Sub-domain Type Value
dotplex1._domainkey CNAME dotplex1._domainkey.dotplex.com.
dotplex2._domainkey CNAME dotplex2._domainkey.dotplex.com.

Autoconfig

Optionally, create the following CNAME record so that some email programs such as Thunderbird can be automatically configured for your domain.

Sub-domain Type Value
autoconfig CNAME autoconfig.dotplex.com.

XMPP

To use your mail accounts with Jabber/XMPP, also add the following DNS records:

Sub-domain Type Value
_xmpp-client._tcp SRV 0 5 5222 xmpp.dotplex.com.
_xmpp-server._tcp SRV 0 5 5269 xmpp.dotplex.com.
_xmpp-server._tcp.conference SRV 0 5 5269 xmpp.dotplex.com.
