# How to use nullhex

## Get a DNS record

 we do not support anything besides custom domains, because we want
 our users to have authority over their email routing, and because
 custom domains are cool af.
 
 I recommend using njal.la for domain purchasing. But use whatever you like!

 for the sake of example, lets pretend we have purchased "garbage.gov"

## Set up all of them pesky records

 Here's the BIND representation of what you need to do. The
 exact steps will differ between DNS providers.

```
 garbage.gov. 3000 IN MX 10 smtp-in-1.nullhex.com.
 garbage.gov. 3000 IN MX 20 smtp-in-2.nullhex.com.
 garbage.gov. 3000 IN TXT "v=spf1 a mx ~all"
 key1._domainkey.garbage.gov. 3000 IN CNAME key1.nullhex.com.
 _dmarc.garbage.gov. 3000 IN TXT "v=DMARC1; p=quarantine;"
 autoconfig.garbage.gov. 3000 IN CNAME autoconfig.nullhex.com.
 _autodiscover._tcp.garbage.gov. 3000 IN SRV 0 1 443 autodiscover.nullhex.com.
 _submissions._tcp.garbage.gov. 3000 IN SRV 0 1 465 smtp.nullhex.com.
 _imaps._tcp.garbage.gov. 3000 IN SRV 0 1 993 imap.nullhex.com.
```

## Test your records

 use our testing script to check whether things are kosher:

 ```
#!/bin/sh

if [ -z "$1" ]; then
   echo "error: domain missing (nullhex.com)"
   exit 1
fi

domain="$1"
errors=""

dig +short MX "$domain" | grep -q 'smtp-in-1.nullhex.com' || errors="smtp-in-1.nullhex.com record not found" 
dig +short MX "$domain" | grep -q 'smtp-in-2.nullhex.com' || errors="$errors\nsmtp-in-2.nullhex.com record not found"
dig +short TXT "$domain" | grep -q '^"v=spf1 a mx ~all"$' || errors="$errors\nspf record not found"
dig +short CNAME "key1._domainkey.$domain" | grep -q 'key1.nullhex.com' || errors="$errors\nkey1._domainkey.$domain record not found"
dig +short TXT "_dmarc.$domain" | grep -q '^"v=DMARC1; p=quarantine;"$' || errors="$errors\ndmarc TXT record is missing"
dig +short SRV "_autodiscover._tcp.$domain" | grep -q '443 autodiscover.nullhex.com.' || errors="$errors\nautodiscover SRV record is missing"
dig +short SRV "_imaps._tcp.$domain" | grep -q '993 imap.nullhex.com.' || errors="$errors\nimap SRV record is missing"
dig +short SRV "_submissions._tcp.$domain" | grep -q '465 smtp.nullhex.com.' || errors="$errors\nsmtp SRV record is missing"
dig +short CNAME "autoconfig.$domain" | grep -q 'autoconfig.nullhex.com.' || errors="$errors\nautoconfig CNAME record is missing"

if [ ! -z "$errors" ]; then
  echo "$errors"
  exit 1
else
  echo "success! u are redy"
fi 
 ```
