This lacks a lot of information to increase the chance for a helpful statement.
What is the script doing but sending a mail?
What means "more"? What was "before", ie. what changed?
If this script is just sending a mail, maybe stop bit coin mining on that box to reduce the performance bottleneck
If the script is performing several steps, identify the slow ones by writing a logfile with timestamps to get a clue what takes so long.
If the script is doing SQL-Statements like in your former posts, contact a DBA and check with him/her, what is going wrong/slow. Maybe some tables/indices etc. changed or resources like CPU/RAM/Storage/Network have been reduced/slowed or someone else is using the host the script is running on, or a possible DB-server extensively.

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.
