### Example

**Path -** `config/plugins.js`

```js
module.exports = ({ env }) => ({
  // ...
  email: {
    config: {
      provider: 'sendmail',
      settings: {
        defaultFrom: 'myemail@protonmail.com',
        defaultReplyTo: 'myemail@protonmail.com',
      },
    },
  },
  // ...
});
```

### Example with DKIM

Using **DKIM** (DomainKeys Identified Mail) can prevent emails from being considered as spam. More details about this subject can be found in the discussion on the Strapi forum: [Unsolved problem: emails goes to spam!](https://forum.strapi.io/t/unsolved-problem-emails-goes-to-spam/512?u=soringfs)

#### Generate the keys using OpenSSL

```perl
openssl genrsa -out dkim-private.pem 1024
openssl rsa -in dkim-private.pem -pubout -out dkim-public.pem
```

**Path -** `config/plugins.js`

```js
module.exports = ({ env }) => ({
  // ...
  email: {
    provider: 'sendmail',
    providerOptions: {
      dkim: {
        privateKey: 'replace-with-dkim-private-key',
        keySelector: 'abcd', // the same as the one set in DNS txt record, use online dns lookup tools to be sure that is retreivable
      },
    },
    settings: {
      defaultFrom: 'myemail@protonmail.com',
      defaultReplyTo: 'myemail@protonmail.com',
    },
  },
  // ...
});
```
