different port numbers

[Marco]

Hi, I wanted to change the port numbers for the mail service (using qmail), while forwarding it from a firewall to the server:   ipmasqadm portfw -a -P tcp -L <fw_address> 25 -R <mailserver_address> xxxx ipmasqadm portfw -a -P tcp -L <fw_address> 110 -R <mailserver_address> yyyy   Is it possible to install Qmail (and possibly manage it subsequently) so that it can respond to port numbers xxxx and yyyy? If so, what should I do? Thank you in advance. Marco [EMAIL PROTECTED]
