Command-Line Email Client

This project is a command-line-based email client that allows users to manage and send emails to official and personal recipients. The email client supports the following features:

Features

1. Recipient Management:

   • The details of official and personal recipients are stored in a text file (clientList.txt).
   • Official recipient records have the format: Official: <name>, <email>, <designation>.
   • Official friends' records include their birthday: Office_friend: <name>, <email>, <designation>, <birthday>.
   • Personal recipients' records include their birthday: Personal: <name>, <nick-name>, <email>, <birthday>.
   • Users can add new recipients to the text file via the command-line.

2. Birthday Greetings:

   • The email client loads recipient details from the text file into the application.
   • On the recipient's birthday, the application sends a birthday greeting email.
   • Official friends and personal recipients receive different birthday messages.

3. Recipient Count:

   • The system keeps track of the number of recipient objects using static members.

4. Email Logging:

   • All emails sent by the email client are saved to the hard disk as serialized objects.
   • Users can retrieve information about all the emails sent on a specific day using a command-line option.

The email client supports the following command-line options:

1. Add a New Recipient:
