*Don't* recommend using a bogus address -- that requires skill on the
part of the user. The list address is "known good", use that.
Problem example: if she's not at yahoo.com and uses a fake yahoo.com
address, DMARC will cause bounces from random users whose providers
respect p=reject. Of course you can mitigate this, but it's just
*one* example, there are plenty of other ways this could go wrong, and
explaining the constraints to the user just isn't worth the effort.
Larry's answer (get a throwaway address) is the one that protects her
privacy best, though. A sufficiently persistent attacker can probably
trace her through the authenticating IP, but that would be a lot of
effort. Use of an alias (eg, AOL screen name) or the Sender header
probably exposes her "real" mailbox far too much for her comfort.
