logins -d

[newtounix]

When running logins -d, I get these outputs:
root 0 other 1 Super-User
smtp 0 root 0 Mail Daemon User

Look like the UID are the same for both root and smtp users. Is this a security risk? If this is the case, how can I safely make the change without affecting the production of the system?

Thanks

The SMTP account also has a user ID 0.
This account is used to facilitate mail transfer, it can not normally logged into. .
