帮我写封英文邮件给学校招生委。解释由于郑州大学邮箱会自动屏蔽外部邮件所以我没有办法使用学校邮件发送这封推荐信只能使用私人邮箱发送推荐信给你们。希望你们能够理解。

Dear Admissions Committee,

I am writing to explain why I am unable to use my Zhengzhou University email address to send this recommendation letter. Unfortunately, the email system at my university automatically blocks external emails, which means I am unable to use my university email to send this letter to you.

As a result, I am using my personal email to send this letter to you. I apologize for any inconvenience this may cause and hope that you can understand my situation.

Thank you for your understanding and consideration.

Sincerely,

[Your Name
