### Example MX Records for Mail Server Routing

Source: https://docs.ossrox.org/Webhosting/DNS/dns-mailserver

These MX records specify the mail servers responsible for receiving emails for a domain, with associated priorities. Lower numbers indicate higher priority.

```dns
example.com.   3600   IN   MX   10 mail.example.com.
example.com.   3600   IN   MX   20 backupmail.example.com.
```

### Example DKIM Record for Email Signing

Source: https://docs.ossrox.org/Webhosting/DNS/dns-mailserver

This DKIM record contains the public key used by receiving mail servers to verify the digital signature of emails sent from the domain. It specifies the version, key type, and the public key itself.

```dns
mail._domainkey.example.com. 3600 IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUA...AB"
```

### SPF Record: Authorizing Servers with External Services

Source: https://docs.ossrox.org/Webhosting/DNS/dns-mailserver

This SPF record authorizes both a specific IPv4 address and an external mail provider (via 'include') to send emails for the domain. '-all' signifies that other servers are not allowed.

```dns
example.com.  3600  IN  TXT  "v=spf1 ip4:203.0.113.10 include:_spf.mailprovider.tld -all"
```

--------------------------------

### SPF Record: Authorizing Sending Servers (IPv4)

Source: https://docs.ossrox.org/Webhosting/DNS/dns-mailserver

This SPF record authorizes a specific IPv4 address to send emails on behalf of the domain. The '-all' mechanism indicates that any other server is not permitted.

```dns
example.com.  3600  IN  TXT  "v=spf1 ip4:203.0.113.10 -all"
```

--------------------------------

### DMARC Record for Monitoring Only

Source: https://docs.ossrox.org/Webhosting/DNS/dns-mailserver

This DMARC record is configured for monitoring purposes only. It specifies that emails failing SPF or DKIM checks should be reported to the provided email address but not rejected or quarantined.

```dns
_dmarc.example.com. 3600 IN TXT "v=DMARC1; p=none; rua=mailto:dmarc-reports@example.com"
```

--------------------------------

### DMARC Record for Strict Rejection

Source: https://docs.ossrox.org/Webhosting/DNS/dns-mailserver

This DMARC record enforces a strict policy, rejecting any emails that fail SPF or DKIM authentication. It also specifies reporting addresses and alignment modes for SPF and DKIM.

```dns
_dmarc.example.com. 3600 IN TXT "v=DMARC1; p=reject; rua=mailto:dmarc-reports@example.com; adkim=s; aspf=s"
```
