iredmail forwarding vs sieve rules

[dev2021-ctrl]

I want to know if iredmail forwardings rules are executed before or after sieve rules.
Example
I added forwarding address for say A user as mentioned here https://docs.iredmail.org/sql.user.mail.forwarding.html
and add sieve rule , something like below

if not (header :contains "From" "XYZ")
{
fileinto "INBOX";
stop;

}
So for if emails is sent to A user and does not have XYZ in from address , will it be forwarded as per the iredMail configuration or just moved to inbox as per the sieve rule.

Pls advise.
A bit urgent

[iRedMail]

• Postfix expands mail alias and forwarding BEFORE sieve rules.
• Sieve rules are applied when Dovecot delivers email to mailbox.
