`SMIMEA` adds a `SMIMEA` record to a domain. The name should be the hashed and stripped local part of the e-mail. 

To create the name, you can the following command:

```bash
# For the e-mail bosun@bosun.org run:
echo -n "bosun" | sha256sum | awk '{print $1}' | cut -c1-56
# f10e7de079689f55c0cdd6782e4dd1448c84006962a4bd832e8eff73
```

Usage, selector, and type are ints.

Certificate is a hex string.

To create the string for the type 0, you can run this command with your S/MIME certificate:

```bash
openssl x509 -in smime-cert.pem -outform DER | xxd -p -c 10000
```
