解析imaplib返回的Message-ID标头

import imaplib
import email

# 连接到邮件服务器
mail = imaplib.IMAP4_SSL("imap.example.com")
mail.login("username", "password")

# 选择要操作的邮件文件夹
mail.select("inbox")

# 搜索邮件
typ, data = mail.search(None, "ALL")
mail_ids = data[0].split()

# 遍历邮件并提取Message-ID
for mail_id in mail_ids:
    typ, msg_data = mail.fetch(mail_id, "(BODY[HEADER.FIELDS (MESSAGE-ID)])")
    msg = email.message_from_bytes(msg_data[0][1])
    message_id = email.utils.parseaddr(msg["Message-ID"])[1]
    print("Message-ID:", message_id)

# 退出并关闭连接
mail.logout()
