Since I always struggle with DNS records for mailservers... here are some examples:
DMARC
_dmarc TXT "v=DMARC1; p=none; rua=mailto:dmarc@domain.tld"
- v - version of DMARC (
DMARC1) - p - policy (
none,quarantine,reject) - rua - URI for agreggate reports (comma-separated)
- ruf - URI for failure reports (comma-separated)
SPF
@ TXT "v=spf1 mx -all"
- v - version (
spf1) - mx - allow emails from servers specified in MX records
- -all - don't allow from everyone else
