Mail provider Amazon SES Inferred from the MX host names: they point to Amazon SES mail servers.
SPF Found The record ends with -all: mail from servers not listed should be rejected (hard fail).
DMARC p=reject The policy is reject: receivers are asked to reject messages that fail DMARC. Aggregate reports are requested (rua).
DKIM Not found among common selectors DKIM can only be confirmed with the selector used by the sender, so this does not mean the domain has no DKIM.
