[SOLVED] Mail Queue to Deferred

[jquiterio]

Hi
All Messages send to another domain and receive from another domain stack on "deferred" mail queues...

help me !!!

You supplied almost no details of your configuration, so it's hard to guess. NExt time describe better what you have.

I guess you are talking about situation of having 2 domains configured in Zimbra, and when user from domain1 sends mail to domain2, mail stucks in deffered queue.

If this is so, my best guess would be you have wrong DNS setup. Your Zimbra is most probably behind firewall on LAN IP, and Zimbra's DNS is setup to query PUBLIC DNS for domain records. So, when Zimbra asks for MX records for domain2, it is told that PUBLIC IP, which is WAN side of your router, is serving it. My guess is that messages cannot pass from LAN via WAN back to LAN, because it's forbidden looping.

Another option is you have something else wrong configured. Check installation guide, especially for host, hostname and DNs settings for Zimbra. If Zimbra is behind router on LAN IP, then also check manuals/wiki for SplitDNS setup, because Zimbra must resolve LOCAL IP from LAN (it's loop I described above)

If not, describe your config, so we don't have to guess.

thinks Labsy,

I have this Scenario:

domain: internet.ao with a: 1.1.1.1 and mx:a, and with ns.domainprovider.ao and ns2.dominprovider.ao

firewall / Router with public ip: 1.1.1.1 (the some with domain "a" record) and gw: 1.1.1.2 (isp router) and lan ip: 172.16.1.8

zimbra
Lan 172.16.0.0/16 where zimbra have 172.16.1.9 with gw: 172.16.1.8
zimbra domain: internetdomain.ao
zimbra smtp host: mail.internetdomain.ao


I was configured dns on zimbra machine with those parameters
ns: 172.16.1.9
a: 172.16.1.9
mx: a (172.16.1.9)

zone "internet.ao"
reverse zone 16.172
forwards: ip of ns.internetdomain.ao

hosts and resolv
/etc/hosts: 172.16.1.9 mail.localdomain.local mail
/etc/resolv.conf: nameserver 2.2.2.2 (the same ns.internetdomain.ao)

I'wrong, but i don't know better configuration for this scenario

sorry about my english


thanks

As I guessed, you must setup Bind DNS server on your Zimbra/Postfix host machine, because your Zimbra/Postfix should NOT get public IP when asking for local domain. Instead, locally installed Bind DNS should return local IP for all local domains.
Solution is called Split DNs or Dual-horizon DNS and is described here Split DNS - Zimbra :: Wiki

With this dns configuration...
how can I setup zimbra ? with "internet.ao" domain or with "localdomain.local" domain ?


Thanks

That means you have a DNS server already listening on that port.

I was configured with parameters described on this site , but up to now, I can not receive mail.

see screenshot please

[jquiterio]

I saw this print on Mail Queues "Host or Domain name not fount, name service error for name=mail.internetdomain.ao type=a, host not fount

Then go to the Split DNS article and run all the commands in the 'Verify...' section of that article to confirm your DNS settinsg & hosts file are correct.

Showing that the email is 'deferred' doesn't help., you need to look in the log files for further information.
