How to send emails via SSH?

Sending emails from the command line in Linux is a valuable skill for system administrators and developers. It allows you to send notifications, logs, or files from a remote server without the need for graphical interfaces.

Connect to the Server via SSH

Open a terminal on your local machine and connect to the remote server using SSH:

$ ssh user@server_ip_address

Replace user and server_ip_address with your username and the server's IP address or domain.

Send a Simple Email

Use the mail command to send an email:

$ echo "Message body" | mail -s "Email subject" recipient@example.com

  • "Message body": The content of the email.
  • "Email subject": The subject that will appear in the email.
  • recipient@example.com: The recipient's email address.

Example:

$ echo "Hello, this is a test email." | mail -s "Test Email" example@example.com

Send an Email with an Attachment

To send an email with an attachment, you can use mutt or uuencode.

Using mutt

First, install mutt if you don't have it:

$ sudo apt install mutt

Then, send the email:

$ echo "Message body" | mutt -a /path/to/file -s "Email subject" -- recipient@example.com

Using uuencode and mail

Install sharutils if necessary:

$ sudo apt install sharutils

Then, send the email:

$ uuencode /path/to/file filename | mail -s "Email subject" recipient@example.com

Sending emails from the command line via SSH is a straightforward task that can automate many processes. With the right tools and this tutorial, you should be able to send emails from your Linux server without any issues.
