[SOLVED] What happens to zimbra mail routing when the web is unavailable?

[ricardoc]

I have a working Zimbra server, that works great delivering/receiving mail.

My question is what if the internet goes down? What I'm hoping to figure out or find among you people is a way to keep internal mail routing happening?

as long as you're using a local dns server, your internal mail should continue to work fine.

I've got local bind working.

I tried recreating a disaster by killing eth1 via linux cli, and zimbra pukes.

Is there a better way to test this?

I'm trying to make sure that mail internally will still get routed if the net goes down.

[bdial]

what'd you do, ifdown it? yeah you don't want to do that because that removes the ip that zimbra binds to. if you're on a single subnet with all your clients and dns server, you could remove the default route to kind of simulate it. or you could do an acl at yoru router to block all traffic.

Yes, i was using IFDOWN haha, woops!

thats a good idea, using acl's

thanks, ill try that and post back

i think we are very close!

I love zimbra so far!

[ricardoc]

ok works great, thanks a lot! I just removed the route to simulate no internet, and zimbra routed internal email just fine, and just queued up external email for delivery later.

Great!
