Hi,
my question is not related to Mailman directly, apologies for using this list. I configured the DNS records for my base domain and my lists subdomain identically (the DMARC policy records are also identical, but not listed here):
MX @ mail.eden.one TXT @ "v=spf1 mx ~all" MX lists mail.eden.one TXT lists "v=spf1 mx ~all"
A mail 123.123.123.123
But both Yahoo and Google report different SPF results for the two domains:
<policy_published> <domain>eden.one</domain> <adkim>s</adkim> <aspf>s</aspf> <p>quarantine</p> <pct>75</pct> </policy_published> <record> <row> <source_ip>123.123.123.123</source_ip> <count>3</count> <policy_evaluated> <disposition>none</disposition> <dkim>pass</dkim> <spf>pass</spf> </policy_evaluated> </row>
<policy_published> <domain>lists.eden.one</domain> <adkim>s</adkim> <aspf>s</aspf> <p>quarantine</p> <pct>75</pct> </policy_published> <record> <row> <source_ip>123.123.123.123</source_ip> <count>2</count> <policy_evaluated> <disposition>none</disposition> <dkim>pass</dkim> <spf>fail</spf> </policy_evaluated> </row>
What could possibly cause this difference? The SPF test also fails for a different base domain with the same MX and SPF records.
