DNS Records
1. General Information
| Record | Description |
|---|---|
| Host | Host name, e.g. - @ = Root domain - * = All subdomains not explicitly configured in the DNS (Wildcard) |
| Type | Record type, e.g. - A = A-Record (Address Record) - AAAA-Record (IPv6 Address Record) - MX = Mail Exchange Record - TXT = Text Record - CNAME = Canonical Name Record |
| MX | For the MX type, a priority is set that determines the order in which mail servers are contacted for the delivery of emails. |
| Destination | Destination of the record. |
| valid | Shows the validity of a record. |
A-Record (Address Record)
Points a domain to an IPv4 address.
AAAA-Record (IPv6 Address Record)
Points a domain to an IPv6 address.
MX = Mail Exchange Record
Indicates the mail server for a domain.
TXT = Text Record
Stores textual information (often for verification or security purposes).
CNAME = Canonical Name Record
Clones the DNS of another domain.
2. Setting DNS Records
- Log in to the Customer Control Panel (CCP).
- Go to the Domains menu item.
- Click the Magnifying Glass Icon next to the desired Domain and switch to the DNS tab.
The following DNS records are relevant for SOGo Groupware. Please note that only the MX record is set automatically. You must enter all other records yourself:
| Host | Type | Destination | Description |
|---|---|---|---|
| @ | MX (10) | mail.mydomain.de (mydomain.de is to be replaced) | Indicates how the mail server can be reached. |
| @ | TXT | v=spf1 mx a include:_spf.webhosting.systems ~all | SPF - allows emails to be sent from the server specified in the A record and in the MX record, as well as from our mail relay. This makes it possible for third parties to recognize whether the email actually comes from the domain owner. |
| key1._domainkey | CNAME | key1._domainkey.webhosting.systems | DKIM – adds a digital signature to ensure that emails have not been altered and come from the rightful sender. |
| key2._domainkey | CNAME | key2._domainkey.webhosting.systems | DKIM – adds a digital signature to ensure that emails have not been altered and come from the rightful sender. |
Both DKIM records (key1 and key2) are required for complete security.
Note that the records will only work as intended if the default DNS settings are used and emails are sent exclusively via the product's mail server. Emails sent via alternative methods such as the web server (e.g. phpmail or sendmail) or an external mail server are excluded and not valid.
