Mail provider Proton Inferred from the MX host names: they point to Proton mail servers.
SPF Found The record ends with ~all: mail from servers not listed should be treated as suspicious but accepted (soft fail).
DMARC p=quarantine The policy is quarantine: receivers are asked to treat messages that fail DMARC as suspicious, for example by delivering them to spam.
