The example above is adapted from Shevek. With respect to VERP, the local part () is moved after her domain name (), further adding a prefix (), a hash ('), and a timestamp ('). That reflects an operational difference: Eventual bounces back to a VERP address are handled within the rewriting domain, and forged messages can at most unsubscribe some users, a kind of abuse that hasn't seen significant exploits in the last decades. Instead, SRS aims at remailing a possible bounce back to "Alice", so that forged bounces can become an alluring technique for injecting spam apparently originating from the rewriting sender.
