Verification Message Issue [Student Pack]

I have a university email, and I tried to add it to my account to get GitHub Student Pack, but I did not receive the verification message. I have contacted my administrator, and the response was that the university mail server is not refusing the message and the problem is from GitHub.

What should I do?
