Allow unique emails to be created on the fly using Auto Keys
I use the services of Sneakemail to prevent my real email being spammed. This is done using an auto key.
An explanation:
Auto Keys are difficult to explain, so instead, here is how they are processed. Assume that you have created a key named "mykey"
Mail comes to Sneakemail servers addressed to myname-mykey@snkml.com
We check if "mykey" exists and who it belongs to.
Does a Sneakemail address "myname-mykey@snkml.com" exist? - yes - use that address.
"myname-mykey@snkml.com" doesn't exist? Create new Sneakemail adress "myname-mykey@snkml.com" using the settings of "mykey" and use that address.
As you can see, a Auto Key is just a template (or a stamp) for creating new Sneakemail addresses.
Once the sneakemail address is created, the key that was used has no linkage to it.
