I have a shadowsocks client listening at 127.0.0.1:8888, and I want to point postfix to that specified port when it try to connect to internet. Put it in another words, I would like to make that address (i.e., 127.0.0,1:8888) something like default gateway so that all my network traffic go through it. Thanks, Yubin
