在提供的引用中，有与局域网邮件收发系统相关的内容。引用[2]提到了基于C语言和TCP Socket实现的Linux环境下的邮件收发客户端程序，不过未给出具体代码。 以下是一个简单的Python示例代码，用于实现基本的邮件发送和接收功能，在局域网中使用需要根据实际情况修改服务器地址和端口等信息： ```python import smtplib from email.mime.text import MIMEText import imaplib import email # 邮件发送函数 def send_email(sender_email, sender_password, receiver_email, subject, body): msg = MIMEText(body) msg['Subject'] = subject msg['From'] = sender_email msg['To'] = receiver_email try: server = smtplib.SMTP_SSL('smtp.example.com', 465) # 替换为实际的SMTP服务器和端口 server.login(sender_email, sender_password) server.sendmail(sender_email, receiver_email, msg.as_string()) server.quit() print("邮件发送成功") except Exception as e: print(f"邮件发送失败: {e}") # 邮件接收函数 def receive_email(receiver_email, receiver_password): try: mail = imaplib.IMAP4_SSL('imap.example.com', 993) # 替换为实际的IMAP服务器和端口 mail.login(receiver_email, receiver_password) mail.select('INBOX') status, messages = mail.search(None, 'ALL') message_ids = messages[0].split() for message_id in message_ids: status, msg_data = mail.fetch(message_id, '(RFC822)') raw_email = msg_data[0][1].decode('utf-8', errors='ignore') msg = email.message_from_string(raw_email) print(f"发件人: {msg['From']}") print(f"主题: {msg['Subject']}") print("内容:") if msg.is_multipart(): for part in msg.walk(): content_type = part.get_content_type() if content_type == 'text/plain': print(part.get_payload(decode=True).decode('utf-8', errors='ignore')) else: print(msg.get_payload(decode=True).decode('utf-8', errors='ignore')) print("-" * 50) mail.logout() except Exception as e: print(f"邮件接收失败: {e}") # 使用示例 sender_email = "sender@example.com" sender_password = "password" receiver_email = "receiver@example.com" subject = "测试邮件" body = "这是一封测试邮件。" # 发送邮件 send_email(sender_email, sender_password, receiver_email, subject, body) # 接收邮件 receive_email(receiver_email, "receiver_password") ``` 需要注意，上述代码中的`smtp.example.com`、`imap.example.com`、邮箱地址和密码等需要替换为实际的信息。
