帮我写封英文邮件给学校招生委。委婉的解释由于郑州大学会屏蔽所有来自外部机构的邮件并且教职员工也不允许发送外部邮件出去所以我只能使用私人邮箱递交这封推荐信希望你们理解。如果有任何疑问请及时与我联系。

Dear Admissions Committee,

I am writing to express my interest in recommending a student for admission to your esteemed institution. However, I regret to inform you that due to the email restrictions imposed by my university, Zhengzhou University, I am unable to send this email from my official university email address.

As you may be aware, my university has a policy of blocking all external emails, and staff members are not permitted to send emails to external organizations. Therefore, I am using my personal email address to submit this recommendation letter. I hope you can understand the situation and accept my recommendation letter through this email.

If you have any questions or concerns, please do not hesitate to contact me. I am happy to provide any additional information or support that may be required.

Thank you for your understanding and consideration.

Sincerely,

[Your Name
