# email_dns.py
|
|
|
|
A Python script to resolve email-related DNS records for a domain.
|
|
|
|
Example:
|
|
|
|
```
|
|
$ python email_dns.py cbarts.net
|
|
{
|
|
"cbarts.net": {
|
|
"mx": [
|
|
{
|
|
"exchanger": "mail.protonmail.ch.",
|
|
"preference": "10"
|
|
},
|
|
{
|
|
"exchanger": "mailsec.protonmail.com.",
|
|
"preference": "20"
|
|
}
|
|
],
|
|
"spf": "v=spf1 a include:spf.protection.outlook.com -all",
|
|
"dkim": [
|
|
{
|
|
"application": "not specified",
|
|
"selector": "default",
|
|
"type": "TXT",
|
|
"value": "v=DKIM1; k=rsa; p=MIIBI...;"
|
|
},
|
|
{
|
|
"application": "exchange",
|
|
"selector": "selector1",
|
|
"type": "CNAME",
|
|
"value": "selector1-contoso-com._domainkey.contoso.onmicrosoft.com."
|
|
},
|
|
{
|
|
"application": "exchange",
|
|
"selector": "selector2",
|
|
"type": "CNAME",
|
|
"value": "selector2-contoso-com._domainkey.contoso.onmicrosoft.com."
|
|
}
|
|
],
|
|
"dmarc": "v=DMARC1; p=quarantine; adkim=s; aspf=s; fo=1; ri=3600;"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Limitations
|
|
|
|
Applications with *dynamic* selector names will not be detected, e.g. smtp2go (`s12345._domainkey.<domain>`) |
