    object-group network dhcp_served_hosts
    network-object 192.168.1.100 255.255.255.252
    network-object 192.168.1.104 255.255.255.248
    network-object 192.168.1.112 255.255.255.240
    network-object 192.168.1.128 255.255.255.240
    network-object 192.168.1.144 255.255.255.252
    network-object 192.168.1.148 255.255.255.254
    network-object host 192.168.1.150

    access-list in2out permit tcp object-group dhcp_served_hosts any eq smtp
    access-list in2out deny ip object-group dhcp_served_hosts any
    access-list in2out permit ip 192.168.1.0 255.255.255.0 any
    access-group in2out in interface inside

    Be careful if you have an external DNS server...
