Send email from telnet

A blast from the past!

Yes, you can send an email using Telnet. Here's a step-by-step guide:

Prerequisites:

  1. You have a Telnet client installed on your computer. If you're using a Windows machine, you can use the built-in Telnet client. On a Mac, you can use the Terminal app.
  2. You have a working email account with a mail server that allows Telnet connections.

Step-by-Step Instructions:

  1. Open your Telnet client and connect to the mail server's SMTP port (usually port 25). For example, if your email account is with Gmail, you would connect to smtp.gmail.com on port 25.

telnet smtp.gmail.com 25

  1. Once connected, you'll see a prompt that looks like this:

220 smtp.gmail.com ESMTP

  1. To send an email, you'll need to issue a series of commands. The basic format is:

<command> <recipient> <subject> <message>

Here's an example:

MAIL FROM: <your_email_address>

Replace <your_email_address> with your actual email address.

RCPT TO: <recipient_email_address>

Replace <recipient_email_address> with the email address of the person you want to send the email to.

DATA

This command starts the email body.

Subject: <subject_line>

Replace <subject_line> with the subject line of your email.

<email_body>

Type the body of your email.

.

This command ends the email body.

QUIT

Here's the complete example:

MAIL FROM: [email protected]

RCPT TO: [email protected]
