To send SMTP mail from localhost, you can use a local mail server software like Postfix or Sendmail. Here is a general guide on how to set up and send SMTP mail from localhost using Postfix:

1. Install Postfix: Install Postfix by running the following command in your terminal: sudo apt-get install postfix
2. Configure Postfix: During the installation process, you will be prompted to configure Postfix. You can choose "Internet Site" as the mail configuration type and enter the fully qualified domain name for your localhost.
3. Modify Postfix Configuration: After installation, you can configure Postfix by editing its configuration file at /etc/postfix/main.cf. You can specify the SMTP server hostname and other settings in this file.
4. Send Mail: You can send mail using the sendmail command. For example: echo "This is a test email" | mail -s "Test Email" [email protected]
5. Test Mail Delivery: Check the mail log to confirm that the mail was sent successfully. You can view the mail log by running the following command: tail -f /var/log/mail.log

Remember to check your local firewall settings to ensure that Postfix is allowed to send mail from your localhost. Additionally, you may need to set up proper DNS records for your domain to avoid having your emails flagged as spam.
