We are using smarter mail to host for our clients. Due to the client requirement need to be using the same mailbox for daily operation.
We are configured POP3 email messages on multiple computers for them and leave the message on server about 90 days.
Recently reported from our client same of the PC can not receive email and I went the Webmail and check all the email has gone.
After trouble shooting, we found that one of the PC has uncheck leave the message from server. We can restore this message on the problem maker PC, but our management is question is that possible to restrict user to do the configuration in their own device
I believe that is not the new issue in this world ,so I would like to seek for expert advice how to overcome this human error issue.
