Sending Mail via Command Line

Ubuntu 11

In the world of system administration, the ability to send emails directly from the command line can be an invaluable tool. This can be used for a variety of purposes, from sending notifications of system events to delivering reports or even automating certain email-related tasks. In this article, we’ll explore several methods for sending mail via the command line, including the use of ssmtp, mail/mailx, sendemail, and mpack.

Quick Answer

Yes, it is possible to send mail via the command line using tools like ssmtp, mail/mailx, sendemail, and mpack. These tools allow you to send emails directly from the command line, making it convenient for system administrators and users who need to automate email-related tasks.

Using ssmtp

ssmtp is a simple tool for sending emails from the command line. To use it, follow these steps:

  1. Install ssmtp using the command: sudo apt-get install ssmtp
  2. Edit the ssmtp configuration file by running: gksu gedit /etc/ssmtp/ssmtp.conf
  3. In the configuration file, append the necessary details such as your email username, password, and mailhub (SMTP server).
  4. To send an email, run: ssmtp recipient_name@gmail.com
  5. You’ll then be able to type your message directly in the command line. Once you’re done, press Ctrl + D to send.

In the ssmtp command, recipient_name@gmail.com is the recipient’s email address. Replace it with the actual email address of your recipient.

Using mail or mailx

Another method is to use the mail or mailx command, which is part of the mailutils package:

  1. Install mailutils with: sudo apt-get install mailutils
  2. To send an email, use the command: echo "test message" | mail -s 'test subject' myemail@mydomain.com

In this command, "test message" is the body of the email, 'test subject' is the email’s subject, and myemail@mydomain.com is the recipient’s email address.

Using sendemail

sendemail is a lightweight, command line SMTP email client. To use it:

  1. Install sendemail with: apt-get install sendemail
  2. To send an email, use the command: sendemail -f fromuser@gmail.com -t touser@domain.com -u subject -m "message" -s smtp.gmail.com:587 -o tls=yes -xu gmailaccount@gmail.com -xp gmailpassword

In this command, -f specifies the sender’s email address, -t the recipient’s email address, -u the subject of the email, -m the message body, -s the SMTP server to use, -o tls=yes enables TLS encryption, -xu specifies the SMTP username, and -xp the SMTP password.

Using mpack

mpack is a tool for encoding files in MIME format. It can be used to send files as email attachments from the command line:

  1. Install mpack with: apt-get install mpack
  2. To send a file as an attachment, use the command: mpack -s "file you wanted" ./data.pdf loser@supergoober.cn

In this command, -s specifies the subject of the email, ./data.pdf is the path to the file you want to send, and loser@supergoober.cn is the recipient’s email address.

Conclusion

These are just a few of the ways you can send mail directly from the command line. Depending on your specific needs, you may find one method more suitable than the others. As always, remember to replace the necessary details like email addresses, usernames, passwords, and SMTP server information with your own. Happy mailing!
