Description
Hi PhysioNet team,
I submitted my credentialing application on June 10, 2026 (username: manwalee).
I discovered that emails between scut.edu.cn (South China University of Technology) and mit.edu are mutually blocked (SMTP error 550 5.4.1). I also confirmed that sysu.edu.cn (Sun Yat-sen University) has the same issue.
I have sent an email to contact@physionet.org with details. Could you please:
- Check if my reference confirmation email was delivered to lyliangzh@scut.edu.cn
- If not, resend from noreply@physionet.org or provide alternative verification
- Note that multiple Chinese institutional email domains may be affected
Thank you!
LEE MANWA
