I do not want to use a wrapper script or any other external method, surely there must be a way to switch users from within the script itself.
Only root can actually
switch users. And even then, you can't do it unless you custom-compile your own
nonstandard perl.
If you want your code to operate in standard perl, within sane safety bounds, and without weird convolutions, you'll have to actually use the system as designed. One process, one user.
So, creating processes inside perl like
su -c perl username and feeding perl statements into the stdin of that process would be one way to go.

INSTALLSIEVE(1) General Commands Manual INSTALLSIEVE(1)

NAME
installsieve - user utility for managing sieve scripts
SYNOPSIS
installsieve
DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server.
OPTIONS
-v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.
-l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
script.
-p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.
-i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully
putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
sieve names may not contain a '.'.
-a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..
-d <name> Delete the sieve script on the server with <name>.
-m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.
-g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is
overwritten.
-u <user> Userid/Authname to use for authentication; by default, the current user.
