如何创建一个可以接收和发送邮件到Zimbra服务器的模块

import smtplib
import imaplib

def send_email(smtp_server, smtp_port, username, password, to_address, subject, body):
    smtp = smtplib.SMTP(smtp_server, smtp_port)
    smtp.login(username, password)
    message = f"Subject: {subject}\n\n{body}"
    smtp.sendmail(username, to_address, message)
    smtp.quit()

def receive_email(imap_server, imap_port, username, password):
    imap = imaplib.IMAP4(imap_server, imap_port)
    imap.login(username, password)
    imap.select("INBOX")
    _, data = imap.search(None, "ALL")
    for num in data[0].split():
        _, email_data = imap.fetch(num, "(RFC822)")
        print(email_data[0][1])
    imap.close()
    imap.logout()

# 使用示例
smtp_server = "your_smtp_server"
smtp_port = 587
username = "your_username"
password = "your_password"
to_address = "recipient@example.com"
subject = "Test Email"
body = "This is a test email."

send_email(smtp_server, smtp_port, username, password, to_address, subject, body)
receive_email("your_imap_server", 993, username, password)
