Mail forwarding wont stop

One at least one of my virtual servers, i have removed and email forwarding, however, even though in virtualmin users, there is no email forwarding for the email account that is doing this, the receiver is still getting emails to their forwarded email address.

I have checked email logss from the account that is sending in virtualmin and its still forwarding emails…even though there are no forwards setup!

If i didnt know better i would say this is a bug of some kind, but perhaps there is another place where this is being overruled outside of the settings in virtualmin for the user email that is doing it?

Can someone explain how this is happening?
