Mailer that uses unique ID for each recipient

[Kendo]

Most of us use one or several email addresses for support and we need to keep changing them as the well gets poisoned. But that cuts off relations and return support requests, so I have been dreaming about a mail system that assigns a unique sender email to every one in its address book. Then we can track the culprits and delete the offenders.

For example if [email protected] emails us then the system adds him to the database and when we we reply our email uses a unique email address. Using [email protected] will not be required if there is a database record that binds something less obvious to that user, such as [email protected]

No doubt there are solutions available like this and it will depend on whether they are server-based, Linux or Windows if we can use them.

I think that the ideal solution would be a web-based support ticket system. But what is available?

Any recommendations?

what happens when someone shares one of these unique email addresses.
let's say someone who is really popular gets great support from you and tells the world about it on twitter.
