martyndavies / legit Goto Github PK

Domains like sharklasers.com are well-known to belong to non legit senders – guerrilla mail in this case. Is there any plan in legit to go beyond MX to include blacklists and whatnot? Else, any suggestions?

Best!

When evaluating an NPM package I like to take a quick peek at the source code. The NPM page for this package doesn't link to this repo, so I had to search through Github to find it.

Passes as legit via package, but when trying to email the account, it is not found.

I tried sending an email directly to [email protected] and I received a failure to send. I then passed the email through the validation using nodejs implementation and it passed validation

test: function (req, res) {
    var checkEmail = require('legit');
    checkEmail('[email protected]', function(validation, addresses, err) {
      if (validation) {
          console.log('This is a real email that can accept emails!');
          console.log(JSON.stringify(addresses));
      } else {
          console.log('This domain cannot accept emails, you might want to remove it.');
      }
    });
  },

On localhost everything works great, but on a test server I get this:

Error validating email:  Error: Error: queryMx EREFUSED gmail.com
    at QueryReqWrap.dns.resolveMx [as callback] (/srv/node_modules/legit/src/index.js:13:16)
    at QueryReqWrap.onresolve [as oncomplete] (dns.js:213:10)

My usage:

async function getInvalidEmails(emails) {
	let invalidEmails = [];
	const promises = emails.map(async (email) => {
		await legit(email)
			.then((result) => {
				if (!result.isValid) invalidEmails.push(email);
			})
			.catch((err) => {
				console.log('Error validating email: ', err);
				invalidEmails.push(email);
			});
	});
  
	await Promise.all(promises);
	return invalidEmails;
}

Any reasons why this might happen?

Seems you only verify domain, but not subdomain of email.

Is there a reason or a technical limitation ?

Hi and thank you for your package module.
i installed and try legit, then uninstall it.

npm r legit
npm uninstall legit

but at start server time, there is an error with legit concerned message:

webpack is watching the files...
internal/modules/cjs/loader.js:638
    throw err;

Error: cannot find module 'legit'

there is no 'legit reference code in source code, i did search with "rg" linux tool application but nothing relative to legit in my code...
Maybe the process to uninstall the package has something wrong/dirty ?
How to fix that, please ?

I like this. Do you have a recommendation on how to process, say, 1000 emails? Does this only check the domain MX records? Maybe I should dedupe the domain first and just check that?

Unfortunately this module can't resolve all legit domains. For example orangelv.com is considered unresolved despite the fact that it has MX records.
The error says:
{ [Error: queryMx ENODATA] code: 'ENODATA', errno: 'ENODATA', syscall: 'queryMx' }
