No homework please, the rules are quite clear and we do not want to be mentionned as "Contract Cheating" site, on the other side we do understand your misfortune, you are the one who will have to show us you work and we will try to guide you or explain your mistakes but do not expect the work be done for you.
That said, lets see what you are up to:
Log when users connect/disconnect can be quite easy but it all depends how the person connects, I usually add a few lines in /etc/profile for that...
Now what about if the user uses ftp, does that count?
and if he connects using remote shell (and so bypasses .profile...)
Good luck

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.
