A global e-mail alias is an alias for all mail sent to your domain that would normally be bounced in this way. Instead of sending the mail back to the sender, it will be instead be sent to the person whose address appears in the global alias.
Many people find global aliasing useful if they want to trap all mail coming to their domain.
They may also want to use several e-mail addresses in their domain and don't want to set up aliases for all of them. Global aliasing is included free in all OxONet accounts, and is accessible via the online control panel .
