原文摘录

摘自原文(866 字符中的一小部分)
Libcurl connection reuse for cleartext-upgrade mail protocols does not include the later transfer's CURLOPT_USE_SSL. If a plaintext connection to one of these protocols is already open and reusable, a later transfer that explicitly requires STARTTLS can incorrectly reuse that plaintext connection.
原文中的代码
python3 ./server.py --port 2525
