Verify email address checking MX records, and SMTP connection.
Install the module through NPM:
$ npm install email-deep-validator --save
Requires Node 7.6 or above
Include the module, create a new EmailValidator
object and call verify
method:
const EmailValidator = require('email-deep-validator');
const emailValidator = new EmailValidator();
const { wellFormed, validDomain, validMailbox } = await emailValidator.verify('foo@email.com');
// wellFormed: true
// validDomain: true
// validMailbox: 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 { wellFormed, validDomain, validMailbox } = await emailValidator.verify('foo@bad-domain.com');
// wellFormed: true
// validDomain: false
// validMailbox: null
A valid Yahoo domain will still return validMailbox
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
.
verifyDomain
Enable or disable domain checking. This is done in two steps:
Default: true
.
verifyMailbox
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 existance.Default: true
.
