What is the *any/*catchall forward?
When processing an incoming mail, E4ward tries to locate a forward in your account which matches the alias and the domain in the email (eg accountname.e4ward.com or yourdomain.com). If there is no such forward, then E4ward locates the forward with alias ‘*any’ and the domain. This is called the catchall forward. As with any other forward, the catchall forward can specify an REA or *bounce. By setting your catchall to bounce, no mail will get through unless it is sent to an alias you specifically added.
