setup multiple domain on a single server

[dl.perez]

Hi All,

I am just a newbie here on zimbra and I just want to know how to setup multiple domain on a single server with a single IP address.

Thanks,
Dan

Hi,

Nothing special unless you need multi domain certificates. Just "zmprov cd nameofdomain" from CLI or go to the admin webui and clic your way through the wizards.

Then you should see all the configurations you can adjust in the web admin UI and try to adjust them...but even if you do not adjust those parameters, the domain is created and functional.

have already done that, it is created and functional but we cannot receive email from the outside, we can send but we cannot receive emails from the outside world.
thanks for the reply

Is the mx record for that domain in public dns severs configured?

Are you able to receive mails for other domains?

[dl.perez]

Hi,

Yes the mx record for that domain is already configured as follows.

Type Name Value
mx mail.seconddomain.com mail.firstdomain.com

Is this setup correct?

Yes, I am able to receive mails from internal zimbra domain.

Thanks for the reply.

That doesn't tell us much, you're going to have to give a bit more detail than that. Go to the Split DNS wiki article and run the relevant dig commands, as shown in the 'Verify....' section of the article, for all your domains then post the output here.

Hi,

This is what I get when I ran the command, dig mail.seconddomain.com

May this results helps.

First of all, you didn't include any MX record info in there as described in the wiki article. Second, in this context, "mail.seconddomain.com" is not a domain it's a hostname. You need valid DNS MX & A records for each of the domains you you host i.e. 'domain1.com' (the primary domain on the ZCS server) then domain2.com, domain3.com etc., etc..... As I've mentioned already, each of those needs their own DNS MX & A records on an external DNS server. Are you running behind a NAT router or firewall?

[dl.perez]

Hi,

Will do that and post the results afterwards.

Yes I am running behind a firewall.

Thanks,

Yes I am running behind a firewall.

In that case you may also need a Split DNS configured to ensure that ZCS gets it's mail delivered correctly or have you already done that?
