Hello,

I have a port problem. I can't figure it out on witch port qmail sends the emails. I have Centos 3 installed and qvcs. I know that usually the emails are send on port 25 but in this case it isn't. The problem is that there are users that must send email with attachments of 1 MB to 50-60 addresses and this is blocking the traffic. I installed HTB for limitation of the exit traffic and of course I limited the 25 port but when the emails are send I see that all the traffic is transmitted on the other ports.

Here it is the HTB configuration:

client client_web {
bandwidth 40;
limit 200;
burst 4;
priority 1;
src {
Ip1/32 80;
Ip2/32 80;
};
};

client client_mail {
bandwidth 40;
limit 150;
burst 4;
priority 2;
src {
Ip1/32 25;
Ip2/32 25;
};
};


client client_restu {
bandwidth 180;
limit 500;
burst 4;
priority 1;
src {
Ip1/32;
ip2/32;
};
};



I have 2 Ip addresses because there is a subnet and I see 2 different ip adresses, the public one and the subnet one for the server.

This is the output of the command show_eth1.


class_1 77.10 24 260 850
client_mail 3.58 0 40 150
client_restu 484.52 24 180 500
_DEFAULT_ 0.00 0 8 8


For the port 80 is working, and by this I mean that when I connect from web mail I see that the traffic is increasing but when sending emails is not using the 25 port.

Please help.
