Let us say I have ID abc.10.user@spamgourmet.com.
Can I add the same ID (abc.10.user@spamgourmet.com) as a trusted sender for this ID (since it appears on the to: for my emails). This would give me an ID that never expires, I hand it to my friends let us say 5 of them.
Later, if this ID gets out and gets spammed, I add my 5 friends as trusted senders for this ID and remove the original as a trusted sender.
This way, if an ID is not being spammed, I am saved the trouble of adding trusted senders one by one or of "recharging" the number of messages on this ID.
