## API / Cloud Hosted Service
We offer this `email verification and validation and more advanced features` in our Scalable Cloud API Service Offering - You could try it here [Email Verification](https://dev.me/products/email)
## Self-hosting - installation and usage instructions
## Installation
Install the module through YARN:
```yarn
yarn add @devmehq/email-validator-js
```
Or NPM
```npm
npm install @devmehq/email-validator-js
```
## Examples
```typescript
import { verifyEmail } from '@devmehq/email-validator-js';
const { validFormat, validSmtp, validMx } = await verifyEmail({ emailAddress: '[email protected]', verifyMx: true, verifySmtp: true, timeout: 3000 });
// validFormat: true
// validMx: true
// validSmtp: true
```
When a domain does not exist or has no MX records, the domain validation will fail, and the mailbox validation will return `null` because it could not be performed:
```typescript
const { validFormat, validSmtp, validMx } = await verifyEmail({ emailAddress: '[email protected]', verifyMx: true, verifySmtp: true, timeout: 3000 });
// validFormat: true
// validMx: false
// validSmtp: null
```
A valid Yahoo domain will still return `validSmtp` true because their SMTP servers do not allow verifying if a mailbox exists.
## Configuration options
### `timeout`
Set a timeout in seconds for the smtp connection. Default: `10000`.
### `verifyMx`
Enable or disable domain checking. This is done in two steps:
1. Verify that the domain does indeed exist;
2. Verify that the domain has valid MX records.
Default: `false`.
### `verifySmtp`
Enable or disable mailbox checking. Only a few SMTP servers allow this, and even then whether it works depends on your IP's reputation with those servers. This library performs a best effort validation:
* It returns `null` for Yahoo addresses, for failed connections, for unknown SMTP errors.
* It returns `true` for valid SMTP responses.
* It returns `false` for SMTP errors specific to the address's formatting or mailbox existence.
Default: `false`.
