Can we send mail from local linux system to gmail

Yes, you can send mail from a local Linux system to Gmail. Here's a step-by-step guide to help you achieve this:

Prerequisites:

  1. You have a Gmail account with 2-Step Verification (2SV) enabled.
  2. You have a Linux system with a mail transfer agent (MTA) installed, such as Postfix or Sendmail.
  3. You have a working internet connection on your Linux system.

Step 1: Configure your MTA

If you're using Postfix, you can follow these steps:

  1. Edit the /etc/postfix/main.cf file using a text editor (e.g., sudo nano /etc/postfix/main.cf).

  2. Add the following lines at the end of the file:

    mydestination = localhost
mynetworks = 127.0.0.0/8 [::1]/128
relayhost = [smtp.gmail.com]:587
smtp_use_tls = yes
smtp_tls_security_level = encrypt

    If you're using Sendmail, you can follow these steps:

  3. Edit the /etc/sendmail.cf file using a text editor (e.g., sudo nano /etc/sendmail.cf).

  4. Add the following lines at the end of the file:

    Dsn4.1.0
FwDsn4.1.0
Msmtp=smtp.gmail.com:587
Msmtp-use-tls
Msmtp-tls-security-level=encrypt

    Step 2: Generate an App Password

To allow your Linux system to send mail from your Gmail account, you need to generate an App Password. Follow these steps:

  1. Go to the Google Account settings page and sign in with your Gmail account.
  2. Click on the "Security" tab.
  3. Scroll down to the "Signing in to Google" section.
  4. Click on "App passwords" and then "Generate".
  5. Select "Mail" as the app type and "Other (Custom name)" as the device type.
  6. Enter a custom name for your app password (e.g., "Linux Mail Client").
  7. Click on "Generate" to generate the App Password.

Step 3: Configure your MTA to use the App Password

If you're using Postfix, you can follow these steps:

  1. Edit the /etc/postfix/main.cf file using a text editor (e.g., sudo nano /etc/postfix/main.cf).
  2. Add the following lines at the end of the file:
    smtp_password = your_app_password

    Replace your_app_password with the App Password you generated in Step 2.

If you're using Sendmail, you can follow these steps:

  1. Edit the /etc/sendmail.cf file using a text editor (e.g., sudo nano /etc/sendmail.cf).
  2. Add the following lines at the end of the file:
    Dsn4.1.0
FwDsn4.1.0
Msmtp-pass=your_app_password

    Replace your_app_password with the App Password you generated in Step 2.

Step 4: Test your mail setup

  1. Send a test email from your Linux system using the mail command (e.g., mail -s "Test email" [email protected]).
  2. Check your Gmail account to see if the email was sent successfully.

That's it! You should now be able to send mail from your local Linux system to Gmail using the App Password.
