Just got a chance to look at this ...

One possibility would be for _email_addresses to call

  _tags -C email-addresses email-$plugins

which would make the context look like

  :completion:*:*:*:email-addresses:*

I'm not sure how $curtag would apply in this case, because it's not set
until _requested or _wanted calls _all_labels from inside the _tags loop?
Or are we talking about nested _tags loops here, which is already a bit
of a sticky wicket?

It's entirely possible that there's some subtlety I'm missing.

On a more general note, though, it would appear that $curtag is rather
under-utilized.  By a quick grep I count about 15 functions that use both
_tags and zstyle without reference to $curtag.  _email_addresses is the
only one that seems to use it as it was intended.
