mailing between different Zimbra mail domains

[john99]

Hello,

As I understand with Zimbra it's possible to configure different (Zimbra) mail-domains :-)


Will such Zimbra-user be able to send/receive mails to users from different Zimbra mail domains "out of the box"?
Or are there some special things to consider/configure ?


Thank you!

John

I'll move this to the correct forum as it's not a question about the Installation of Zimbra (which is where you posted).

Yes.

Will such Zimbra-user be able to send/receive mails to users from different Zimbra mail domains "out of the box"?

Of course you can send mail to each of the domains on the same server.

Or are there some special things to consider/configure ?

Only the same things you'd configure for a single domain e.g. DNS A & MX records.

Thank's for the help Bill!

Should that work as well, if the Postfix-MTA and Fetchmail are not yet installed/configured properly (e.g. for demonstration purposes) ?


Thank you!

PS:
But if Split-DNS is working properly :-)

I don't quite understand that question. The Postfix-MTA on your server is not required (if that's what you're talking about) by zimbra nor is fetchmail (that just gets mail from an external accounts).

But if Split-DNS is working properly :-)

If you already have a Split DNS set-up then just adding DNS A & MX records for the additional domain(s) will allow you to send mail between each of those domains. You'd also need valid DNS A & MX records for the additional domain(s) on an external DNS server so that they can additionally receive mail from the internet.

Ok the following was our db.lan.mycompanyname.com file:

************************************************** ******
-> ; BIND data file for local loopback interface
-> ;
-> $TTL 604800
-> @ IN SOA nsizhma01.lan.mycompanyname.com. admin.nsizhns01.lan.mycompanyname.com. (
-> 9 ; Serial
-> 604800 ; Refresh
-> 86400 ; Retry
-> 2419200 ; Expire
-> 604800 ) ; Negative Cache TTL
-> ;
-> @ IN NS nsizhns01
-> @ IN MX 10 nsizhma01
-> nsizhns01 IN A 10.0.1.50
-> nsizhma01 IN A 10.0.1.10

************************************************** ******
PS:
- nsizhns01 IN A 10.0.1.50 (this is the DNS-server)
- nsizhma01 IN A 10.0.1.10 (this is the mailserver/ZCS)
************************************************** ******


Question:
Do you mean, the additional mail-domains should have been added just after the following entries ?

@ IN SOA nsizhma01.lan.mycompanyname.com. admin.nsizhns01.lan.mycompanyname.com.



Thank's a lot for any additonal feadback!

I would appreciate additional help very much in order to be able to set up a running Zimbra environment soon :-)


Thank you very much!

I've already given you the answer to this just add additional records for the new domain. Go to the Split DNS and see the requirements for the BIND DNS server (I don't like the format you're using for your records).

If you want an easier way to manage the DNS you could install webmin on your server.

Thank's a lot Bill for the help!

I don't like the format you're using for your records.

Thank's, I am willing to learn :-)


Originally I was not my intention to have different mail domains. According my "log-file", during installation of Zimbra, i get the following message:

DNS Error resolving MX for nsizhma01.lan.mycompanyname.com
It is suggested that the domain name have an MX record configured in DNS
Change doamain name? [Yes]yes
Create domain: [nsizhma01.lan.mycompanyname.com]lan mycompanyname.com


Was this [Yes] the reason that finally in the Zimbra-Admin GUI, I had the following mail domains ?

- (admin@)lan.mycompanyname.com[/email]
- (user@)mycompanyname.com[/email]


Thank you!

John


PS
Unfortunately I am not sure anymore if during installation of Zimbra my zone file looked really the way I posted it in this thread ...

[phoenix]

Thank's, I am willing to learn :-)

It's just a personal preference but I prefer that the monain and FQDN of the server is spelt out, that way it's easier to see if you have the correct domain and you can easily add multiple domains without too much confusion.

Was this [Yes] the reason that finally in the Zimbra-Admin GUI, I had the following mail domains ?

Yes it was the reason. When doing the initial installation Zimbra will, if you enter 'No', use the FQDN of your server as the domain name. Is this all working correctly now?

Thank you very much Bill for your help. I promise that I am soon going to (re-)install Zimbra :-)

Best regards,

John


PS
This was an old issue and I was at this point in time not able to install ZSC properly.
