How to Retrieve Emails with POP3 in Python using Aspose.Email

As a Python developer, you value simplicity and efficiency in your code. Aspose.Email for Python perfectly aligns with your goals, offering an intuitive Python Email API that allows you to securely connect to a POP3 server, retrieve emails, access message content, and save them in .eml format without the hassle of complex configurations or processes. Try a straightforward and intuitive code sample to check this.

Create a POP3 Client Instance

Using the aspose.email library to access the email handling API, create a Pop3Client object, specifying the server address, port (993 for SSL), and the user’s credentials (username, password). The client is responsible for connecting to the POP3 server.

import aspose.email as ae
with ae.clients.pop3.Pop3Client("pop.example.com", 993, "username", "password") as client:
    client.security_options = ae.cliets.SecurityOptions.AUTO

The security_options property is configured to automatically negotiate the best security protocol using SecurityOptions.AUTO. This ensures a secure connection to the mail server.

List Emails on Server

The list_messages() method is used to retrieve a list of email message metadata from the server. This provides essential information, such as the subject, sender, and date.

    for msg_info in client.list_messages():
        # print info about email
        print(f"Subject: {msg_info.subject}")
        print(f"From: {msg_info.from_address}")
        print(f"Date: {msg_info.date}")
        print("------------")

Download Emails

The fetch_message() method is used to download the full email message using its unique identifier (unique_id). This fetches the email’s content, including attachments if any.

        # fetch email
        eml = eml.fetch_message(msg_info.unique_id)

Save Emails to .eml Format

Finally, the downloaded email is saved as an .eml file using the save() method. The filename is dynamically generated based on the email subject, which provides a convenient way to store the messages.

        # save email
        eml.save(f"{eml.subject}.eml")
