No; for revisions where I'm only listed as a subscriber, I'm in CC, for 
revisions where I'm reviewer or author, I'm in the TO field.

Hmm, maybe. The issue is pretty much the reverse - if I'm listed as 
explicit subscriber but also subscribe to the "project", those mails would 
still have the same tags.

So is there a way to distinguish mails where I'm an explicit tagged 
subscriber (and thus in CC, also e.g. for reviews where I've taken part in 
discussion) and I'm also getting them via the project subscription (so the 
mail does have all the tags for subscription delivery)? Or would I be 
getting two mails for that situation, once for the project subscription 
and once for personal subscription to the individual review?
