So do not wonder why Thunderbird fails.

I definitely advise you to look at firewall rules and log to ensure you can access.
What is very strange to me is that you can access using IP.
Can you try to make it simple, from Thunderbird standpoint (for testing purpose) and set up your SMTP server using port 25 (no TLS, no auth...)?

nothing block in firewall.
still with no tls and auth mydomain timeout

1 - did you try, from command line:

Code: [Select]

telnet 25 mail.mydomain.com
2 - Did you look at firewall logs for rejected or dropped packets?

Connecting To 25...Could not open connection to the host, on port mail.mydomain.com: Connect failed

I realize now that you made some effort to hide everything in your previous attachment reason why I tough name was not resolved (I read it too quickly too  )

However I notice you can't ping (reach ?) it.

PS: no need to hide your internal IP (192.168.42.x): this is RFC1817 compliant => no one will access it from outside 
even in your last reply, you replace your DNS IP with xxx. Who cares if this is 192.168.42.1 or 192.168.42.254?

192.168.42.1 is the firewall server
192.168.42.2 is the zentyal server (mail server).
at client i can ping the mail.mydomain.com or the ip address of zentyal server.
but when connect using thunderbird time out

Is 192.168.42.1 your Zentyal server?
Type, from your client:

Code: [Select]

nslookup mail.mydomain.com

Server:  xxx.mydomain.com (firewall)
Address:  192.168.xxx.xxx

Non-authoritative answer:
Name:    mail.mydomain.com
Address:  xxx.xxx.xxx.xxx

your last capture is showing that you even can't resolve this name at OS level (while you explained the opposite  ) thus there is no chance it works using Thunderbird 
Could you please post the result of:

Code: [Select]

ipconfig /all

I suspect - again - something wrong client side.
Look at attached pic. This is how it looks on my own Thunderbird (Ubuntu).

same with mine

Hello yudidw2,

Since the start of this thread, have you rebooted your PC ?

You may also try to flush your DNS:
1) Click Start

2) Search for "cmd.exe" (it should start your shell)

3) type:

Code: [Select]

ipconfig /flushdns
4) restart ThunderBird and test

**Also, please make sure that you leave the DNS auto-configuration to your desktop.  See this howto if you aren't familiar with this configuration:
http://support.microsoft.com/kb/323380/en

Keep us updated.

Best,

Marcus

already done that, but still thunderbird can't connect to the server.
all pc in office cannot connect via thunderbird to that mail server (domain.com)

so, to summarize:
- Thunderbird is configured to user mail.yourdomain.com as smtp server

correct

- on this same PC, if you type "ping mail.yourdomain.com" it resolves this name and reaches mail server
- .... but from Thunderbird, you get time out
correct ?

correct

Frankly I did look yet at your postfix conf. I don't think any problem there would generate this behaviour.
However, looking at your DNS settings, it appears that you do not describe "smtp" but "mail". I'm not surprised you can't resolve "smtp". I'm surprised you try to use it.
As you have defined everything with "mail", configure Thunderbird with "mail" instead.

Then last point will be to understand why, assuming problem still exists, "mail.yourdomain.com" is not found from Thunderbird.
I rather suspect some typo or use of host name instead of fqdn 

ok... i use mail.domain.com at thunderbird but problem still exist.
what should i do? where i can change ?

« on: April 20, 2012, 03:20:23 am »

so, you have 2 different issues if I understand well:

- your DNS doesn't contain any entry for smtp.domain.com  (but do you need one as mail.domain.com already exists and can be used)
- Thunderbird doesn't work when using FQDN. Strange    are you sure that config is really the same when switching from IP address to FQDN? I mean in term of port to be used, TLS, authentication ...

did you mean DNS settings in zentyal ebox menu?
In Domain name server resolver I entered with the ip address of DNS domain.
In Infrastructure DNS menu list of domain I entered with :
domain.com --> hostname  : mail, mail exchanger : mail, name servers : mail
ip address : 192.168.1.10 (local ip)

btw, are mail.domain.com and smtp.domain.com supposed to be same server (Zentyal hehehe)?
If yes, why not using mail.domain.com in your Thunderbird conf?

it is the same server, but using mail.domain.com or smtp.domain.com always getting connection timeout.
when i use manual config and set smtp server to local network ipaddress(zentyal), the message succesfully send
