英文高手帮忙把下列中文翻译成英文

Dear Mr. Pekco,

Hi!

Our employees often get those calls complaining about receiving several copies of the same email from our company. However, we're convinced that we sent only once.At the same time, we meet the same problem when receiving emails from others.
We wonder if there's something wrong with the server, please figure out the reason. Thank you!

Mr. Pekco,
hello!
These two days, when the staff were receiving their e-mails, they would often receive the phone from the other side, saying that he has received more than ten letters of the same content. However, we are sure that we have only sent one letter. And we are also in the same situation with the other side.
Is there a problem of the Mail Server. please check the cause for this problem.
Thanks
