[O] Emacs org-mode mailing list filter by category / tag?

[Buddy Butterfly]

Hi,

obviously this is a very active forum.
But due to the activity I am getting too much
emails. I would like to filter by tag/category
when registering. I think this is definitely
needed to reduce the amount of mails before (!)
it arrives.

Is this possible right now? If so, how?
If not, could this list be enhanced to provide it?

Cheers,
Matt
