Auto mail configuration in gr

In GR (Gnu Radio), you can configure auto-mail to send emails with various settings. Here's a step-by-step guide:

Prerequisites:

1. Install the gr-mail block from the Gnu Radio Companion (GRC) or using the gr-modtool command-line tool.
2. Make sure you have a working email account and the necessary credentials (username, password, and SMTP server).

Configuring Auto-Mail in GR:

1. Open the Gnu Radio Companion (GRC) and create a new flowgraph.
2. Drag and drop the gr-mail block from the "Utilities" category into the flowgraph.
3. Double-click on the gr-mail block to open its properties.
4. In the "General" tab, set the following:
   • To: Enter the email address you want to send the email to.
   • From: Enter the email address you want to send the email from (your email account).
   • Subject: Enter the subject of the email.
5. In the "SMTP" tab, set the following:
   • SMTP Server: Enter the hostname or IP address of your email provider's SMTP server.
   • Port: Enter the port number used by your email provider (usually 25 or 587).
   • Username and Password: Enter your email account credentials.
6. In the "Body" tab, set the following:
   • Body: Enter the text you want to send in the email body.
   • Format: Choose the format of the email body (plain text or HTML).
7. Click "OK" to save the changes.

Sending an Email:

1. Run the flowgraph by clicking the "Run" button or pressing F5.
2. The gr-mail block will send an email with the configured settings.

Tips and Variations:

• You can use variables to customize the email content, such as using the gr-variable block to set the email subject or body dynamically.
• You can also use the gr-mail block in combination with other blocks, such as gr-file or gr-socket, to send emails based on specific conditions or events.
• If you're using a Gmail account, you may need to enable "Less secure app access" in your account settings to allow Gnu Radio to send emails.

Remember to test your email configuration by sending a test email before using it in your actual flowgraph.
