I now have a toaster server with multiple ip addresses bound to the WAN
Nic. Qmail-smtpd automatically listens on both ip addresses inbound (eth0
and eth0:0), but by default qmail-remote binds to only the first (eth0)
outbound.
In a situation where eth0 is down (with only eth0:0 available), this
causes qmail-remote to hold messages in queue until eth0 becomes available
again. Are the following qmail control options available for
qmail-remote--e.g. patched into the toaster distribution? If so, what
would be the best configuration utilizing these control options--e.g. to
always have qmail-remote bind to the IP address on eth0 when available,
but to automatically fail to the IP address on eth0:0 when eth0 is not
available? Or would I need a script to update one of these control files
that executes automatically during a failover to the IP on eth0:0 when the
IP on eth0 is not available?
bindroutes (qmail-remote)
Any mail sent from an specific source IP address will be sent from the
given IP address.
The entry in bindroutes looks like this:
source ip:ip
Example for bindroutes:
# network 10.x.x.x
10.:1.2.3.4
# network 10.10.x.x
10.10.:1.2.3.4
# network 10.10.10.x
10.10.10.:1.2.3.4
# host 10.10.10.10
10.10.10.10:1.2.3.4
# rest
:1.2.3.4
# don't send any mail to this
1.2.3.4:
If qmail-remote is not able to bind to that IP address then the message
will stay in the queue until the problem has been corrected.
senderip overwrites bindroutes.
and/or
senderip (qmail-remote)
Any mail sent from an email address in the given domain will be sent from
the given IP address.
The entry in senderip looks like this:
domain:ip
If qmail-remote is not able to bind to that IP address then the message
will stay in the queue until the problem has been corrected.
