Configure DMARC, SPF, and DKIM records at Hostnet, one of the Netherlands' most established hosting providers. Complete DNS guide for email security.
Introduction
Hostnet is one of the longest-running and most trusted hosting providers in the Netherlands, offering domain registration, web hosting, email services, and website builders. Now part of the team.blue group, Hostnet combines Dutch reliability with European scale. If your domain is registered or hosted with Hostnet, this guide will show you how to configure DMARC, SPF, and DKIM for comprehensive email authentication.
Hostnet provides a modern control panel that makes DNS management accessible even for non-technical users. Follow these steps to secure your email in about 10 minutes.
Email Security Fundamentals
Every day, billions of emails are sent worldwide, and a significant percentage are fraudulent. Email spoofing -- where attackers forge the "From" address to impersonate your domain -- is one of the most common attack vectors. DMARC, SPF, and DKIM are the international standards designed to combat this threat. They are supported by all major email providers including Gmail, Outlook, Yahoo, and many more.
Without these records, your domain is essentially unprotected. Anyone can send emails claiming to be from your domain. Check your current protection level at https://dmarcanalyzer.pro/tools/dns-checker.
Step 1: Log In to Hostnet
Navigate to https://www.hostnet.nl/account/ and log in with your Hostnet customer account. After logging in, you will see your Hostnet control panel with an overview of your domains, hosting packages, and email services.
Step 2: Open the DNS Editor
Click on "Domeinen" (Domains) in the main navigation. Find your domain and click on it to view its details. Look for "DNS instellingen" (DNS settings) or "DNS beheer" (DNS management). Click on it to open the DNS zone editor. Hostnet's DNS editor shows all current records in a clear table format. You can add, edit, and remove records from this interface.
Step 3: Add Your SPF Record
Click the button to add a new DNS record (typically "Record toevoegen" or "+ Add record"). Select "TXT" as the record type. Set the host/name to @ (root domain). In the value/content field, enter: v=spf1 include:_spf.hostnet.nl ~all.
If you use additional email services, include them all: v=spf1 include:_spf.hostnet.nl include:_spf.google.com ~all. Important: Only one SPF record per domain. If Hostnet has already created a default SPF record, edit it to add your additional providers. Save the record.
Validate your SPF record at https://dmarcanalyzer.pro/tools/spf-checker to confirm it is correctly formatted and within limits.
Step 4: Add Your DKIM Record
Click "Add record". Select "TXT". In the host/name field, enter selector._domainkey (replace "selector" with the DKIM selector from your email provider). Paste the DKIM public key value. Save.
Hostnet email users: Hostnet may already have DKIM signing enabled for their email hosting. Check the "E-mail" section of your control panel. If DKIM is active, the corresponding DNS record should already exist in your zone. You can verify by looking for existing records containing "_domainkey" in the hostname.
Step 5: Add Your DMARC Record
Click "Add record". Select "TXT". In the host/name field, enter _dmarc. In the value field, enter: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.nl; ruf=mailto:forensic@yourdomain.nl; fo=1; adkim=r; aspf=r. Save the record.
Starting with p=none is the recommended approach. You collect data without affecting email delivery. After analyzing reports for a few weeks, you can increase enforcement. Use the DMARC Record Builder at https://dmarcanalyzer.pro/tools/dmarc-builder for a customized record.
Step 6: Verify Your Setup
Hostnet DNS changes typically propagate quickly. Wait 15 to 30 minutes, then verify at https://dmarcanalyzer.pro/tools/dns-checker. The tool checks all three records and provides a clear pass/fail status for each. If any record shows an issue, return to Hostnet's DNS editor and double-check the values.
Hostnet-Specific Features
DNS templates: Hostnet may offer DNS templates for common configurations. Check if they have an email security template that pre-populates recommended records.
Email scanning: Hostnet's email hosting includes spam and virus scanning. DMARC, SPF, and DKIM complement these features by preventing outbound email spoofing -- protecting not just your inbox but your domain's reputation.
Multiple domains: If you manage several domains through Hostnet, you will need to configure email authentication for each one separately. DMARC Analyzer Pro supports multi-domain monitoring from a single dashboard.
