Minimal DNS configuration¶
# Name Type Value @ IN MX 10 mail.example.com @ IN TXT v=spf1 mx -all
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
Add created public key as TXT record under
# Name Type Value dkim._domainkey IN TXT v=DKIM1; k=rsa; t=s; s=email; p=DKIM YOUROWNKEY
