I actually have that as well.

I have this as well, or similar. I do not have a homedirectory set that
seems to work at the moment, so I have it as a full path.

Thank you for the VirutalUsers/Home. This will help. I spent a lot of
time reading various documentation and somehow missed this.

Is there some global option like mail_location for homedirectory? That
is one I am not finding one with google or with grep in the configuration.

I have done this as well. The problem with removing all of this is I use
Dovecot's deliver (LDA). It needs a way of finding which users do and do
not exist. Is there a better way to do this?

I may be able to turn this off. I do use postfix and I believe it is
already looking up the users. I seem to remember there was an option to
turn this off in Dovecot (the looking up of the user for LDA).

The only problem that is there is this: I need doveadm expunge -A. This
is where I am having the problem. I guess this doesn't use the user_
stuff. It uses the iterate_attrs right?

vmail and root are NOT in the AD LDAP.

This is what I get when I run doveadm search -A mailbox INBOX from
VALID_FROM
