Validating whether e mail is legit
Using a similar logic, we can verify an email address from the computer without actually sending an email message.
Here’s how: Let say that we want to verify if the address [email protected] or not?
Then it tells you whether the email address is real or not.
Some mail servers do not co-operate in the process, in such cases, the result of this email verification tool may not be as accurate as expected.
This nslookup command will query name servers for that domain.
Since we have specified the type as MX, our command will extract and list the MX records of the email domain.
When you send an email to someone, the message goes to an SMTP server which then looks for the MX (Mail Exchange) records of the email recipient’s domain.
If you are a marketer, you can be sure that your promotions reaches to your target audience or if you are businessmen, you can know whether your contact has shared correct info or not. Whenever a new person gives you his/her email address to you, you can simply send a greetings/welcome mail to validate their address.
Go to Gmail and type the email id you received and click on ‘Forgot Password’.
If it’s not a valid email ID, Gmail will notify you.
Pick any one of the servers listed in the MX records, maybe the one with the lowest preference level number (in our example, gmail-smtp-in.l.google.com), and “pretend” to send an email message to that server from your computer.
Email Checker is a simple tool for verifying an email address. It extracts the MX records from the email address and connect to mail server (over SMTP and also simulates sending a message) to make sure the mailbox really exist for that user/address.
