Minimal DNS configuration

# Name                Type        Value
@                     IN MX 10    mail.example.com

To explicitly allow our mailserver to send mails from your domain we recomment to add an SPF record to your DNS zone.


Please make sure to include all other servers that should be able to send mails from your domain.


DKIM is an email authentication method designed to detect email spoofing. While it is not required to add those records, we recommend to do so.

Generate a new key for this domain through the webinterface. Use the following settings:

Domain: example.com
Selector: dkim
DKIM key length: 2048 bits
create dkim key

Add created public key as TXT record under dkim._domiankey:

# Name              Type       Value
dkim._domainkey     IN TXT     v=DKIM1; k=rsa; t=s; s=email; p=DKIM YOUROWNKEY
