Remove email.ncu.edu.cn from stoplist — Nanchang University email migrated to Coremail with student ID verification

[88lin]

Request to remove email.ncu.edu.cn from the stoplist

Background

email.ncu.edu.cn is currently in the stoplist (lib/domains/stoplist.txt), which prevents all students at Nanchang University from using their @email.ncu.edu.cn email addresses to apply for JetBrains free educational licenses.

The parent domain ncu.edu.cn is already in the repository (lib/domains/cn/edu/ncu.txt), so the only thing blocking recognition is this stoplist entry.

Why it should be removed

The email system has migrated from Tencent Enterprise Email to Coremail (campus email), with strict student identity verification.

1. Old system (Tencent Enterprise Email): The @email.ncu.edu.cn domain was previously hosted on Tencent Enterprise Email (exmail.qq.com). This likely allowed administrators to create accounts for non-students, which is probably why it was added to the stoplist.

2. New system (Coremail campus email): As of July 2026, Nanchang University has migrated the student email system to Coremail. The new login portal is at http://mail.email.ncu.edu.cn/.

3. Strict student verification: The new system requires student ID + real name verification for account activation. The activation page (http://mail.email.ncu.edu.cn/edu_reg/userActive/index) has a 3-step process:

   • Step 1: Identity verification — requires Student ID and Full Name
   • Step 2: Phone binding — phone number verification
   • Step 3: Set password — create account password

   Only enrolled students with valid student IDs can activate email accounts. This eliminates the abuse vector that likely caused the domain to be stoplisted.

4. Migration documentation: The official migration guide is published at https://365.kdocs.cn/l/crumIhltZkxQ (titled "Email Data Migration Guide v2 - Students", updated 2026-07-28), confirming this is an institutional migration.

Evidence

• University official website: https://www.ncu.edu.cn/
• New email login portal: http://mail.email.ncu.edu.cn/ (Coremail, Copyright 2026 Nanchang University)
• Account activation page (requires Student ID): http://mail.email.ncu.edu.cn/edu_reg/userActive/index
• IT-related courses: Nanchang University has multiple IT-related colleges:
  • School of Software: http://soft.ncu.edu.cn/
  • School of Information Engineering: http://ie.ncu.edu.cn/
  • School of Mathematics and Computer Science: http://smcs.ncu.edu.cn/
  • School of Artificial Intelligence: http://sai.ncu.edu.cn/

Note

The old Tencent email domain alias email2.ncu.edu.cn is NOT in the stoplist and currently works for JetBrains applications. However, this domain alias will be deprecated as the migration completes. The new system uses email.ncu.edu.cn (Coremail), which is the one being stoplisted. Removing this entry ensures students can continue to apply for JetBrains educational licenses after the migration is complete.
