Continually receiving the same emails

Hi

I have received emails from 4 different senders over the past 12 days which keep being sent to me every few minutes. These are not junk mail, and I want to continue to receive emails from these senders.

I have tried deleting the messages and transferring the senders’ details to the Junk email folder, but I have received over a thousand emails in the past day alone. How can I stop these emails from being received, but continue to receive emails from the senders?
Thanks 
Andrew

Hi,

Can you please go to tools>operations and copy the logs from the third tab when this occurs?
Thanks.
