I have a start-up company.
We started using the Zimbra e-mail tool provided through an external company (which also hoosts it).
A year ago, they installed it and asked us for the DNS requirements.

Right now we are in a conflict...

My question is (I am not a tech person):
is it possible that the hoosting provider (w/administrator role) sent mails in the name of the created users?

For what I read, as administrator (and hoosting providers) they can check all of my company´s users mailboxes.

But COULD they have sent mails in the name of the users themselves to other partys???

Many Thanks,
