---------------------------
Hello [~btellier],
Thank you for the clarification. That explanation makes sense, and the current
behavior is acceptable.
Could you please let me know when the PR is expected to be approved and merged?

> When performing an SPF check using
> org.apache.james.jspf:apache-jspf-resolver:1.0.4, the process hangs
> indefinitely during the DNS resolution phase. The issue is observed with the
> following SPF check:
> {code:java}
> String spfResult = new
> DefaultSPF().checkSPF("207.54.72.202","do_not_re...@unicredit.de","esa13.hc437-5.eu.iphmx.com").getResult();{code}
> The log indicates the process gets stuck at the A-Record lookup for the
> domain 207.54.72.202.spf.hc210-93.eu.iphmx.com, with repeated debug messages
> until it eventually times out after multiple hours:
> {code:java}
> [ForkJoinPool.commonPool-worker-1] DEBUG
> org.apache.james.jspf.core.MacroExpand -- Domain expanded:
> 207.54.72.202.spf.hc210-93.eu.iphmx.com

> This issue does not occur with version 1.0.3, where the SPF check completes
> successfully.
> *Steps to Reproduce:*
> Use org.apache.james.jspf:apache-jspf-resolver:1.0.4.
> Perform the SPF check with the provided code snippet.
> Observe the logs and notice the process getting stuck at the DNS
> resolution step.
> *Expected Result:*
> The SPF check should complete without hanging, as it does in version 1.0.3.
> *Actual Result:*
> The SPF check hangs indefinitely during DNS resolution, eventually timing out
> after several hours.{*}{*}
> *Version:* org.apache.james.jspf:apache-jspf-resolver:1.0.4
> *Previous Working Version:*
> org.apache.james.jspf:apache-jspf-resolver:1.0.3
