Qmail send port unknown
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. |
