Install the module through YARN:
yarn add @devmehq/email-validator-js
Or NPM
npm install @devmehq/email-validator-js
import { verifyEmail } from '@devmehq/email-validator-js';
const { validFormat, validSmtp, validMx } = await verifyEmail({ emailAddress: 'foo@email.com', 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:
const { validFormat, validSmtp, validMx } = await verifyEmail({ emailAddress: 'foo@bad-domain.com', 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.
timeout
Set a timeout in seconds for the smtp connection. Default: 10000
.
verifyMx
Enable or disable domain checking. This is done in two steps:
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:
null
for Yahoo addresses, for failed connections, for unknown SMTP errors.true
for valid SMTP responses.false
for SMTP errors specific to the address's formatting or mailbox existence.
Default: false
.yarn test
