Since you gave a fake UID, and no GID it is hard to tell.  When posting,
you can change the username, but leave the UID as is.  If that number is
so critically sensitive, then you should probably not ask your question
in a public forum and instead seek assistance via more private
communications.


Special UIDs-

Is the actual UID below a threshold so that the system thinks it is a
system or admin user, subject to different restrictions?  These
thresholds vary, but 1000, 500 and 100 are common.


SELinux-

Are you running the SELinux extensions which would impose additional
restrictions?


ACLs-

Do you have ACLs (filesystem or Dovecot) that would affect this user
differently?


Groups-

You stated that the user is a Roundcube admin.  Is the user in the same
group as the rest of your normal mail users or a special group for the
Roundcube functions?

Do you need to manually add the user to the group for regular mail users?

What are the group settings on your directories?

Could it be the group permissions that is giving access to most users?
