帮我写封英文邮件给学校招生委。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 submit a letter of recommendation for a prospective student. However, I regret to inform you that due to the email policy at Zhengzhou University, all emails from external institutions are blocked and faculty and staff are not permitted to send external emails. Therefore, I am unable to submit this letter through my university email.

As a result, I am submitting this letter through my personal email account. I apologize for any inconvenience this may cause and hope that you understand my situation.

If you have any questions or concerns, please do not hesitate to contact me. Thank you for your understanding and consideration.

Sincerely,

[Your Name
