To me it looks like packets go through:

[root@xxx ~]# tcpdump | grep some_external_ip

15:21:21.365433 IP some_external_ip.37849 > postfix_server_internal_ip.pop3: S 3011648941:3011648941(0) win 5840 <mss 1452,sackOK,timestamp 450822963 0,nop,wscale 6>

15:21:26.058233 IP some_external_ip.42605 > postfix_server_internal_ip.smtp: S 3092138727:3092138727(0) win 5840 <mss 1452,sackOK,timestamp 450823431 0,nop,wscale 6>
