Think this should do what you describe:

Code:
nalias() {
   local fulline="$*"
   local xalias=${fulline#*=}
   local name=${fulline%%=*}
   local pre=${name%%\**}
   local i

   [ "$pre" == "$name" ] && name=""
   name=${name#${pre}\*}

   for((i=0; i <= ${#name}; i++))
   do
      alias $pre${name:0:$i}=$xalias
   done
}

Of course for i in $(seq 0 ${#name}) can be used in place of the above for(( code for more compatibility with older shells, at the cost of some speed.

Pearls before swine could be abbreviated PBS

NAME
local.users - Specifies mail recipients on the local host. DESCRIPTION
The local.users file contains a list of user names whose mail is to be delivered to the local host and whose return address is user- name@hostname. Entries in the local.hosts file are in addition to other local users (such as root and postmaster). See sendmail.cf(4) for a description of other local users. You can add entries to this file if the host is configured as a simple client and either of the following is true: The user wants their mail delivered on this machine rather than being forwarded to the mail server. You are adding aliases to the /var/adm/sendmail/aliases file. When the host is configured as a simple client, the alias must be added to this file and the aliases file. A simple client is defined as a host that had the mail system configured using the MailConfig application from the System Management utili- ties or configured using the mailsetup utility's Quick Setup menu. The format of the file is as follows: User names are separated by blanks or new lines. Multiple user name can be specified on a line. Blank lines are ignored. A comment mark (#) ends the line. After modifying the local.users file, you must restart the sendmail daemon to apply the changes. Use the following command: # /sbin/init.d/sendmail restart EXAMPLES
root postmaster rw # A comment followed by an ignored blank line. # Another comment. mariah # Another comment. carey # Leading blanks are acceptable. FILES
Specifies the path name for the file. RELATED INFORMATION
