allegro.pl domain score

Your domain has basic email authentication in place. Consider strengthening your configuration for better protection.

Top Recommendation

+10

Add aggregate reporting (rua) to receive DMARC reports

DMARC improvement

allegro.pl has a DMARC record but no reporting configured, limiting visibility into authentication results. SPF is correctly configured with a strict policy (-all), specifying which servers may send on its behalf. A few improvements would strengthen allegro.pl's email authentication posture.

Entry:

v=DMARC1; p=quarantine; adkim=r; aspf=r; rf=afrf;

Without a reporting address (rua), you won't receive aggregate reports from email providers. These reports show who is sending email as your domain and whether authentication passes or fails.

Macro

Dynamic SPF macro - counts as 1 potential lookup when evaluated at delivery time

SPF Macro Variables:

%{i} = sender IP address

This mechanism uses SPF macros that are expanded when an email is received. The actual domain queried depends on the sender's IP address and other connection details.

TLS-RPT (Reporting)

TLS-RPT Not Configured

Publish a TXT record at _smtp._tls.allegro.pl with v=TLSRPTv1 and reporting URI (rua=).

MTA-STS (Policy)

MTA-STS Not Configured

Publish a TXT record at _mta-sts.allegro.pl with v=STSv1 and policy ID (id=).

Protect inbound transport

You've checked your outbound authentication. But without MTA-STS and TLS-RPT, mail delivered to allegro.pl isn't protected against transport downgrade attacks. Receiver Shield helps you deploy, monitor, and safely enforce transport security.

Know when your DNS records change

The check you just ran shows your current configuration. But DNS records change, sometimes without you knowing. A well-meaning IT change, a third-party provider update, or an unauthorized modification can break your email delivery overnight.

Configuration Drift

IT changes that accidentally break authentication

Provider Updates

Third-party services changing their SPF includes

Unauthorized Changes

Attackers modifying records to send as you

DMARCTrust monitors your DNS records continuously. When something changes, you get an email alert with exactly what changed and why it matters. No more surprises when customers complain their emails bounced.

About This Checker

What we check

We analyze your domain's email authentication: DMARC policy and alignment, SPF record and includes, and BIMI logo and certificate status when present.

Why it matters

Healthy authentication improves delivery and blocks spoofing. Major inbox providers increasingly expect DMARC and aligned SPF/DKIM from senders.

Included features

  • DMARC syntax, policy, and reporting validation
  • SPF record evaluation and include analysis
  • DKIM/SPF alignment interpretation
  • BIMI record and VMC detection
  • Clear setup and remediation guidance

Monitor your email authentication 24/7

This check shows a snapshot. With DMARCTrust, you get continuous monitoring of your DMARC reports and DNS records, with instant alerts when something changes.
