Confused email problem with some clients

Dear all,
I have some clients on my domain and they are having a strange problem
with their email.
“Recipient is receiving the email more than one ( 6 to 10 times and sometime 25 ) if that email has any attachment.” they said.

There is no problem on the configuration of outlook.

Anyone have any idea about it?

Thank you and Regards,
