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.

uuconv

uuconv(1)						      General Commands Manual							 uuconv(1)

NAME

       uuconv - convert UUCP configuration files

SYNOPSIS

       uuconv -i type -o type [-p program] [--program program]

       uuconv --input type --output type [-p program] [--program program]

DESCRIPTION

       The  uuconv program can be used to convert UUCP configuration files from one format to another.	This can be useful for administrators con-
       verting from an older UUCP package.  Taylor UUCP is able to read and use old configuration file formats, but some new features can  not	be
       selected using the old formats.

       The type of configuration file to read is specified using the -i or --input options.  The type of  configuration file to write is specified
       using the -o or --output options.

       The supported configuration file types are taylor, v2, and hdb.	For a description of the taylor configuration files, use the info  command
       and  see "*Note Configuration Files::" for uucp.  The other types of configuration files are used by traditional UUCP packages, and are not
       described in this manual.

       An input configuration of type taylor is read  from  a compiled in directory by default.

       The output configuration is written to files in the directory in which uuconv is run.

       Some information in the input files may not be representable in the desired output format, in which case uuconv will silently  discard  it.
       The output of uuconv should be carefully checked before it is used.  The uuchk(8) program may be used for this purpose.

       The  -p	or  --program  option may be used to convert specific cu configuration information, rather than the default of only converting the
       uucp configuration information.

OPTIONS

       -i, --input
	    Set input type (one of taylor, v2, hdb)

       -o, --output
	    Set output type (one of taylor, v2, hdb)

       -p, --program
	    Program to convert (e.g., uucp or cu)

	      Standard UUCP options:
	      -v, --version Report version information and exit.

       --help
	    Print a help message and exit.
