Thunderbird is a free, open-source email client, popular as a lightweight alternative to Outlook.
Adding Your Account
Open Thunderbird, go to Account Settings > Account Actions > Add Mail Account, and enter your name, email address, and password.
Manual Configuration if Needed
If auto-detection doesn't find the correct server settings, choose manual configuration and enter your IMAP and SMTP server details from your welcome email or Plesk directly.
Confirming It Works
Send a test email to yourself once configured to confirm both sending and receiving are functioning correctly.
