[SOLVED] Installing on hosting dedicated server

[ttortosa]

Hello,

My enterprise has rented a dedicated server to an external hosting enterprise.

The machine hostname is (for exemple): enterprise.dedi.hosting.net, however I'm trying to install zimbra for our domain enterprise.com. Must I change the hostname machine?

If I don't change it, I can't retrieve webpages entering either enterprise.dedi.hosting.net:81 neither enterprise.com:81.

We installed apache, and then I use 81 port for zimbra to avoid port conflicts.

Thanks

You can have the hostname set to enterprise.dedi.hosting.net as long as a A and MX record is present in DNS. You can then set the MX record for enterprise.com to point to the hostname enterprise.dedi.hosting.net.

Thanks uxbod.

I've this in db.enterprise for bind9 configuration, following your instructions:

;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA enterprise.com. root.enterprise.com. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN MX enterprise.dedi.hosting.net
@ IN A 127.0.0.1


And a declared zone taking this file (db.enterprise). Is this sufficient for access to zimbra?

Will I need to modify my /etc/hosts file? May someone help me, please? Thanks!

The BIND entry you have created is for the localhost loopback address. Has your hosting provided given you a public or private IP address for your server ? I guess they will provide the DNS so they just need to setup a MX record for enterprise.com that points to enterprise.dedi.hosting.net.

Really need a little bit more information to help so could you post the following please

cat /etc/hosts
cat /etc/resolv.conf
dig enterprise.dedi.hosting.net
dig enterprise.com mx
host `hostname` <- note backticks and not double quotes

obertic.dedi.acens.net is the server hostname
obertic.com is the domain that I want to get working for

cat /etc/hosts

217.116.20.173 obertic.dedi.acens.net

cat /etc/resolv.conf

search acens.net
nameserver 127.0.0.1
nameserver 217.116.0.178
nameserver 217.116.0.179

dig enterprise.dedi.hosting.net =>
dig obertic.dedi.acens.net

host obertic.dedi.acens.net

Host obertic.dedi.acens.net not found: 3(NXDOMAIN)

(Because of Zimbra is not working, now I've postfix on. But when I install zimbra, I stop postfix, couriertcpd, and amavisd)

Thanks uxbod

Okay, thanks for that. All that needs to be done then is for your hosting company to change the MX record for obertic.com to the following

IN MX 10 obertic.dedi.acens.net.

you will also need to remove nameserver 127.0.0.1 from your resolv.conf. Any resolution should now be performed by your hosting providers DNS and email for obertic.com should be routed to your ZCS server. Ensure ZCS is installed and working before switching the MX record. You should also ask your hosting provider if they will setup a secondary MTA for your domain, with a lower priority MX, incase your server fails. That way you shall not loose any email.

Thanks, thanks, and thousands of thanks!

Now I've working properly zimbra and I can send emails, but not receive, surely because our provider still not changed the mx record.

Thanks

Correct

dig obertic.com mx
