# The default receiving port in the Fedora and RHEL SELinux policy is 10024.
# To allow additional ports you need to label them as 'amavisd_recv_port_t'
# For example: semanage port -a -t amavisd_recv_port_t -p tcp 10022
$inet_socket_port = 10024;   # listen on this local TCP port(s)
# $inet_socket_port = [10022,10024];  # listen on multiple TCP ports
