Hello, Recently noticed some "domain not found" errors by reject_unknown_sender_domain in sender_recipient_checks. Following up I noticed :
The domain in the From: address has a SPF record (ONLY) : nslookup -q=ANY kent676.kent.gov.uk kent676.kent.gov.uk text = "v=spf1 ip4:194.80.130.18 ip4:212.219.86.147 ~all" The ip's do match the MX's for the main domain (kent.gov.au) though. But no A or MX records, as you might suspect (so the error is valid) : nslookup -q=A kent676.kent.gov.uk *** Can't find kent676.kent.gov.uk: No answer nslookup -q=MX kent676.kent.gov.uk *** Can't find kent676.kent.gov.uk: No answer I guess this is just "wrong" in that there should be an A or MX record. Are the allowed DNS record types for reject_unknown_sender_domain configurable ? Should they be ? I guess in this case the servers generate mail only. Cheers Brett
