The user is "newuser" and the uid is 1111 (actual name and number changed to protect the innocent).
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?
