qmail and virtual IPs

[Martin Hasenbein]

Hi,

I have installed a few virtual ip-adresses yesterday
to have my webservers and my mailserver on different IPs.
Like this:

fxp0: flags=8843 mtu 1500
inet 192.168.0.3 netmask 0xfff0 broadcast 192.168.0.15
inet 192.168.0.5 netmask 0x broadcast 192.168.0.5
inet 192.168.0.6 netmask 0x broadcast 192.168.0.6
inet 192.168.0.7 netmask 0x broadcast 192.168.0.7
inet 192.168.0.8 netmask 0x broadcast 192.168.0.8
inet 192.168.0.9 netmask 0x broadcast 192.168.0.9
inet 192.168.0.10 netmask 0x broadcast 192.168.0.10
inet 192.168.0.11 netmask 0x broadcast 192.168.0.11
inet 192.168.0.12 netmask 0x broadcast 192.168.0.12
inet 192.168.0.13 netmask 0x broadcast 192.168.0.13

My server has the 192.168.0.3 and the mailserver should run on 192.168.0.5.
But when I'm now sending eMails its acting from the 192.168.0.3, not
from the virtual ip-address. How can I change that?

Thanks

You'll need to patch qmail-remote for this.  Go to 
and search for either "fixed IP address" or "bind the local address".  I
personally prefer the latter, as the mechanism used (bindroutes) is more
flexible, but the former is easier to configure if you only ever have a
single IP address to bind to.

You cannot. qmail-remote doesn't use a specified IP address for sending
mails, that's up to the system. If memory serves me right your colleague
maex has a patch for qmail-1.01 to use a specified IP; if not there may be a
link on qmail.org. Otherwise it should be easy changeable in qmail-remote.c

Greetings
