**Third**, add new DKIM DNS record of `TXT` type for subdomain `postmoogle._domainkey` that will be used with postmoogle.
You can get that signature using the `!pm dkim` command:

<summary>!pm dkim</summary>
DKIM signature is: `v=DKIM1; k=ed25519; p=OcVzOwAONDfgbJX/5vwzlXOs9gUDO0YKlXHaDnBJtXw=`.
You need to add it to your DNS records (if not already):
Add new DNS record with type = `TXT`, key (subdomain/from): `postmoogle._domainkey` and value (to):
```
v=DKIM1; k=ed25519; p=OcVzOwAONDfgbJX/5vwzlXOs9gUDO0YKlXHaDnBJtXw=
```
Without that record other email servers may reject your emails as spam, kupo.
