Is there a way to automatically delete duplicate emails received from a single private server? I am on several email lists on this server and if an email is sent to any one of these such as officers@ I get 2 copies of the email. If it is sent to say officers@ and info@ I will get 4 copies. If it is sent to me and any one of these addresses I get 3 copies. All the copies are exact duplicates. For some reason the server can not stop this and I am the only person that seems to have this issue. I would like to automatically delete these duplicates.
