Issue postfix hangs after lots of restarts when deleting a lot of domains or domain aliasses at once

I tried to create a issue report but keep getting this message:
"Oops! We ran into some problems. Please try again later. More error details may be in the browser console."

so i'll post it here for now

when deleting a subscription/domain with a lot of domains aliasses, hostings and mail alliasses, plesk keeps sending postfix a restart command and postfix eventualy hangs.

Systemd is preventing the restart of the postfix service for some time due to too many restarts.

Workaround:
# systemctl edit postfix.service

Then paste the following:
Code: 
[Service]
StartLimitInterval=0

Then reload:
# systemctl daemon-reload
 
Thanks for the workaround, but that's not the issue.

I know this configuration exist but i should not have to change the default systemd on dozens of servers. Plesk should not send so many restart requests. If i have these problems, then less linux knowledgeable users will have the same problem and they can not alter systemd.

btw, its actualy:

systemd < 230 (centos 7 = 2.19)

[Unit]
StartLimitInterval=

systemd > 230 (almalinux, centos 8 = 2.39)

[Unit]
StartLimitIntervalSec=
