Rietveld automatically sent emails to reviewers with a "+reviewer" suffixed to the username. Gerrit appears not to do this--it sends emails to just <username>@chromium.org.  This borks my mail filters and worse, I can't figure out any way to fix them--gmail appears to consider -rdsmith@chromium.org as applying to both rdsmith+watch@ & rdsmith+cc@, so I can't send things on my watchlist that I haven't been asked to review to a separate folder.

(My apologies for the high priority, and you're welcome to set it down on the basis that this is just one developer, but it's very likely I'm going to have to mass remove myself from watchlists unless I can find some way to do this filtering properly.)
