![]() - The email account that you tried to reach is disabled.- The email account that you tried to reach does not exist.You’ll get an “OK” if the address exists else a 550 error like: The server response for ‘rcpt to’ command will give you an idea whether an email address is valid or not. 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.), and “pretend” to send an email message to that server from your computer.įor that, go to the command prompt window and type the following commands in the listed sequence:ģc: Identify yourself with some fictitious email addressģd: Type the recipient’s email address that you are trying to verify: As you may have noticed in the nslookup output, it is not uncommon to have multiple MX records for a domain. MX preference=5, exchanger = gmail-smtp-in.l. Replace with the domain of the email address that you are trying to verify. Since we have specified the type as MX, our command will extract and list the MX records of the email domain. This nslookup command will query name servers for that domain. At the command prompt, type the nslookup command: ![]() Enable telnet in Windows or use the PuTTy tool. Let say that we want to verify if the address exists or not? Using a similar logic, we can verify an email address from the computer without actually sending an email message. If the records exist, the next step would be to determine whether that email username ( hello in our example) exists or not. ![]() 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.įor instance, when you send an email to the mail server will try to find the MX records for the domain. PS:Some web domains may have configured a catch-all email address meaning that messages addressed to a non-existent mailbox will not be returned to the sender but in most cases, such email messages will bounce. How do you verify if a given email address is real or fake? The obvious solution is that you send a test mail to that email address and if your message doesn’t bounce, it is safe to assume* that the address is real.
