If you have a certain e-mail address that you do not wish to accept mail for, you can disable that address. This is particularly useful if you receive a lot of spam at an address you no longer want to use.
If you don't have the Catch-All Alias turned on, then you're getting mail at this address because it was added to your account management control panel. You can simply delete the address in question:
Because the address will no longer exist, messages sent to it will be rejected.
If you're using the Catch-All Alias, the instructions above won't be sufficient, because the Catch-All Alias will continue to accept messages sent to addresses that don't exist.
In that case, a little trick will help: you can create a forwarding alias to reject@tigertech.net, which is a special value that tells our servers to reject the message.
To do that, first follow the instructions above to delete the address if it appears in the "POP Mailboxes" or "Forwarding Alias" sections of the control panel. (If you were already receiving mail at the address in question only because of the Catch-All Alias, you don't need to delete anything.)
Then:
Any messages sent to that address will be automatically rejected (if they come from outside of our network) or discarded (if they're sent from inside our network). You'll never see them (and there is no way for us to retrieve them, so be sure you really want to do this).
