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
