收件服务器怎么填

import smtplib
import imaplib

# SMTP服务器配置
smtp_server = 'smtp.example.com'
smtp_port = 587
smtp_username = 'your_email@example.com'
smtp_password = 'your_password'

# IMAP服务器配置
imap_server = 'imap.example.com'
imap_port = 993
imap_username = 'your_email@example.com'
imap_password = 'your_password'

# 发送邮件示例
def send_email(to, subject, body):
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(smtp_username, smtp_password)
    message = f'Subject: {subject}\n\n{body}'
    server.sendmail(smtp_username, to, message)
    server.quit()

# 接收邮件示例
def receive_email():
    mail = imaplib.IMAP4_SSL(imap_server, imap_port)
    mail.login(imap_username, imap_password)
    mail.select('inbox')
    _, data = mail.search(None, 'ALL')
    mail_ids = data[0].split()
    for mail_id in mail_ids:
        _, msg_data = mail.fetch(mail_id, '(RFC822)')
        print(msg_data[0][1])
    mail.logout()

# 调用示例
send_email('recipient@example.com', 'Test Subject', 'This is a test email.')
receive_email()
