New server can send, cant recieve.

[rslrdx]

Hi,

I've installed bind9 on the server, and the dns service is up and running, nslookup on the hosted domain works, I can still send emails from the zimbra server, but I can not recieve yet, however, now I do not get an error anymore, not even in the logs. My question now is, Where did the message go? I cant see errors, neither as a returned mail or any other type. so, anyone has any ideas out there for me?

One note, I cant even get a reply from the server if i send it to an user that really doesnt exist, which normally would give me an error.

Another thing i noticed, when i get an email from the server and look in the header i see that the mail server name is the host name, not the domain name. Any thoughts on that?

Thanks.

Moment after I posted the last update I recieve an email from the server that I used to send messages to the zimbra host, and it says its has not been able to deliver the email for 4 hours...

at this point i only have one dns server on my /etc/resolv.conf file, should i add another?

and btw, i do have another dns server on the network, the original one, so, wouldnt it make sense to just make it work on that one instead of installing a new one?

TIA,
Rodrigo.

if you are expecting to receive external email on the above domain then you need to update your external DNS MX record.

well, thats not the domain, you tried it with mail.maisveloz.com.br, thats the isp, not my server.

any other thoughts?

Well the other domain listed in your /etc/hosts gets the following

 dig carlostavares.com.br mx

so what is your domain ? you need to get your external MX record pointing to your internal ZCS server or it will never receive external email. Or are you using fetchmail to collect the email from your ISP ???

The domain is carlostavares.com.br.
there are other domains hosted on the same network, and since we're migrating from exchange, but have not yet completed, the other domains are still pointing to the old exchange server, and port 25 was directed to that server. I did change port 25 to the new server just to test it, sent an email from outside, and now I get a different error message, not the 550. 5.7.1 anymore. now it says it cant deliver, it was saying that before port 25 was re-routed, but even after i route it to the new server, still not delivering.

One other detail, the external mx records point to the correct ip address, however, when you do telnet to the domain, you were getting an answer from the exchange server that hosts all domains because of port 25 being routed there... once i route it to the correct server, i get a simple message saying "connected" but no info on what the server is, I assume thats zimbra. i cant keep the other domain down for long, once i make this single domain work, i will copy the settigns to the other domains and do a user migration.

Hi, and TIA

I did noticed some new things and perhaps this will get fixed soon..

Like I said before, the dns server was installed, as per the instructions on the wiki, and I didnt get the returned mail automatically anymore, but mail was not delivered either and the servers trying to deliver the message would just keep on trying untill they just gave up.

As of right now, I cant recieve any mail, even if the message is sent to someone else in the zimbra server. Any ideas of why it would do that?

Here is a very important question, I will be hosting other domains othe same server, do I just add more zones to bind ?

I noticed in the syslog some errors from the dns server, I wonder if they have anything to do with it. One thing I find odd is that the wiki tells me to create a mail.domain.com entry in the bind server as a zone, but, from my little experience, I belive I would actually enter domain.com as a zone, and mail.domain.com as an A record, and then the MX record for it as well, But this is a split domain, and that might be why its working like that, can anyone confirm that this is correct?

I just looked in the admin panel, there is a check mx records, even with the dns lookup and dig working from the CLI, that check fails. The SMTP host name shown there is the internal domain name, which only works behind the firewall, and then it shows that it found the mx record for the correct domain, but they dont match. that just might be the root of all this problems.

Anyone has any idea what of I should do next? I dont think changing the hostname will help, as I'm going to deploy 3 other domains on the same server.

should I setup an alias for the internal domain on the dns server? As of right now it only contains the information based on the split dns wiki.

Thanks

BIND is not setup correctly anyway for your domain

please post named.conf and the associated zone files.
