This is an exim alias under wikimedia.org, so ops has to do it, it's not lists.wikimedia.org (and if it were, this request would have to go to the lists' admins rather than a Wikimedia-Mailing-lists ticket anyway)

Thank you for correcting me. I got the same request from Rachel Stallman to have Yana removed from this other legal alias: legal-reports@wikimedia.org

They are unsure what other alias' she is apart of, so is it possible to just search for her email and then remove her from all of it?

I think @Andrew is the person dealing with these tickets this week (?)

Unless the underlying account is being closed, it might be a good idea to find out exactly which aliases point there before removing all of them
