To work around this issue, we modified the code to match both the From and To addresses against the exclusive sender text. But when the exclusive sender text matched the disposable address itself, this had the unintended side effect of matching *every* message that was To: the address (not CC or BCC, btw), essentially pegging the address open. We decided to leave it at that, knowing that, without proper documentation (or maybe even with it), there was no way that a statistically significant percentage of the addresses would wind up in this state, but those users who *really* wanted to peg open addresses still could.
Thanks for describing this in detail, Josh. I have now updated several of my exclusive senders to better match how I want them to work (a few of them previously matched the disposable address).
And thanks for continuing to provide a great service!
