When mail is sent from my server, Qmail uses an incorrect IP for the connection. How do I change the IP used for outgoing connections from my server?

  • Parallels Plesk for Linux/Unix


The default IP for outgoing connections can be set using the "ip" utility. First, check how routing is configured on the server:

# /sbin/ip route dev eth1 proto kernel scope link src dev eth1 scope link
default via dev eth1

If no "src" is listed in the "ip" output for the default route, the main IP on the interface is used for outgoing connections. You can change it using the following command:

# /sbin/ip route change default via dev eth1 src


/sbin/ip route dev eth1 proto kernel scope link src dev eth1 scope link
default via dev eth1 src

Note: Be careful. If you set the wrong IP as the source, you will lose the link to the server.

Additional Information

To preserve this result after reboot on SLES10, you must insert the following lines into the /etc/sysconfig/network/if-up.d/staticroute file:

/sbin/ip route change default via dev eth1 src
/sbin/ip route change dev eth1 src
