# Configuring authentication at Antagonist

> Add the CNAME and DMARC records for Laposta in DirectAdmin under DNS management.

On the page [Authentication with your domain provider](/authenticatie-instellen-bij-je-domeinprovider#which-records-to-add), you can see which records you need to add.

1. Log in to [mijn.antagonist.nl](https://mijn.antagonist.nl/).
2. Select ‘Producten’ (Products) and click on your domain.
3. On the right-hand side, select ‘Hostingpakket beheren’ (Manage hosting package). This will take you to DirectAdmin.
4. On the left-hand side, select ‘Accountbeheer’ (Account management) and then ‘DNS-beheer’ (DNS management).
5. Click on ‘Record Toevoegen’ (Add Record) and enter the two CNAME records. If Laposta indicates this, also add the DMARC record (TXT).

For each record, enter the record type, the name and the value:
