Registered User

While it is not necessary, it is recommended that you get rid of the 'UUCP' users. [uucp & nuucp]
Since they belong to a 'system' that is RARELY used.

You do this by executing the 'pkgrm' command for the two UUCP packages: SUNWbnuu && SUNWbnur.

Which (respectively) are 'Basic Networking Utilities (User)' and 'Basic Networking Utilities (Root)'.
[Remove in that order.]

They are usually considered security risks, and are really not much use unless there is a modem attached to the computer.

The 'nobody && noaccess' users are sometimes used as IDs to run certain processed as, to make the processes less likely to cause harm if 'hacked'.

Netscape used to run the 'httpd' as 'nobody' by default, some folks run Apache as that user.

The 'smmsp' user is what sendmail runs it's 'listen' process as, and the 'listen' user is a left over from the AT&T System V Release 4 OS (which was the original 'root OS' that Solaris grew out of).
The 'listen' user no longer is used, BUT, as you said, there might be 'stuff' lingering around that requires it.

NAME

       errors - Contains a record of uucico daemon errors

SYNOPSIS

       /usr/spool/uucp/.Admin/errors

DESCRIPTION

       The /usr/spool/uucp/.Admin/errors file contains a record of uucico daemon errors that the uucp program cannot correct.  For example, if the
       uucico daemon is unable to access a directory that is needed for a file transfer, the uucp program records this in  the	errors	file.	If
       debugging is enabled for the uucico daemon, the uucp program sends the error messages to standard output instead of to the errors file.

EXAMPLES

       Following   is  the  text  of  an  error  that  might  appear  in  the  errors  file:  ASSERT ERROR (uucico) pid: 303 (7/18-8:25:09)  SYS-
       TAT OPEN FAIL /usr/spool/uucp/.Status/ (21) [SCCSID: @(#)systat.c   7.2 87/07/08 16:43:37, FILE: systat.c, LINE:100]

       This error occurred on July 18 at 8:25:09 a.m.  [(7/18-8:25:09)] when the uucico daemon, running as process 303 [(uucico) pid: 303],  could
       not  open  the  /usr/spool/uucp/.Status directory [SYSTAT OPEN FAIL /usr/spool/uucp/.Status/].  To prevent this error from occurring again,
       you should make sure the permissions for the .Status directory are correct.  It should be owned by the uucp login ID and group  uucp,  with
       permissions of 777 (read, write, and execute for owner, group, and all others).

FILES

       Contains  the  errors file and other uucp administrative files Lists the last time a remote system was contacted and the minimum time until
       the next retry
