Hi All,
You wish to changed your Qmail mail server's outgoing IP address with these following steps:
Suppose that the qmail IP address is 10.01.10.2 and we want to change it to 10.10.10.3. Please note the gateway IP address should not be changed.
==============>>>
root#/sbin/ip route
x.x.x.x/16 dev eth0 scope link metric 1002
x.x.x.x/8 dev eth0 proto kernel scope link src 10.10.10.2
default via 10.10.10.1 dev eth0 proto static
----------------------------
Run this command to change the mail server IP:
# /sbin/ip route change default via 10.10.10.1 dev venet0:1 src 10.10.10.3
----------------------------
Done, you have successfully changed the mail server IP.
Enjoy!~
