Ali Mail (@aliyun.com): Bind Directly With Login Password (No App-Specific Password Needed)
⚠️ Ali Mail (@aliyun.com) stopped new user registrations from 2025-03-26 — existing users continue to use it. Simplest configuration — bind to Laifaxin directly with your login password, no 2-Step Verification or app password needed (unlike Gmail / QQ / 163). IMAP/SMTP services on by default.
