Question to mailheader with $spam_quarantine_to

hi everybody,

the option:

$allowed_added_header_fields{lc('Received')} = 0;

is disabled.

if i enable the option:

$spam_quarantine_to

then the spam redirect contains the amavisd mailheader with "(amavisd-new, port 10024)"

how can i disable the mailheader with the enable option $spam_quarantine_to?

i wish this to hide my used tools.

i am using centos 8.

kind regards.
