Error when FW mail to me domain.

[cmenghi]

When I try to forward an email to someone within my domain this mail does not arrive, but if forwarding to an external account does arrive, this happens if sent separately.
If I put in a mail forwarding my domain and one from outside no problem.

sorry, my English is not good

What error messages do you see in the log files and have you set-up a Split DNS (you need one if you're behind a firewall or NAT router).

Thank you for responding

He gave no errors since its installation four months ago, started to do some three weeks ago, after upgrading (Release 6.0.6_GA_2330.UBUNTU8_64 UBUNTU8_64 FOSS edition.)

The error occurs only with referrals within the same domain, not to external addresses and does not always happen. Any idea ?

You're really not giving much information about the problem. Have you looked in the log files to see if the message was delivered? Does this happen to one specific user or all forwarded mail? I've also asked you if you have set up a Split DNS in your LAN, have you and is it working correctly?

Thanks for responding.
The message was sent folder, but postfix logs are not, and this only happens when we want to send emails within the domain, if we send out wrong. All users go inside the lan and not always happen, but it is random. As reciver and send out emails from external domains to work without problem.
Im setup Split DNS using the internal DNS pointing directly to Zimbra MX
And pointing to the external FW is doing against the zimbra relay.

The strange thing is that it worked properly, so we update (6.0.4> 6.0.5> 6.0.6.1) and do not send emails to users randomly from the same domain, has baffled me. I have the slightest idea that the webmail to SMTP will not deliver properly.

thakns to enlighten in this problem

Can you provide some evidence that it's set-up sorrectly? Go to the SPlit DNS article and look at the 'Verifying...' section and provide the information from that section.

I don't understand what this means.

Your hosts file is incorrect, the following line should replace the one in your file:

127.0.0.1 localhost.localdomain localhost

You resolv.conf should only contain your LAN DNS server i.e. the following is all that should be in it:

search paysandu.gub.uy
nameserver 172.16.42.4

Make those changes, reboot your server and try again. When you done that you can try forwarding an email (tail the log file while you're sending it) and see what happens.

When one user of ours REPLY or FORWARD some email to internal AND external mailboxes, SOMETIMES (not always) the external mailbox receives the email BUT the internal mailbox doesn't receive anything.
Taking a look to the LOG files, it seems to me that everything works properly.


The client is OUTLOOK 2007
The client OS is Windows Vista

Below our /etc/hosts and /etc/resolv.conf

#hosts
127.0.0.1 localhost.localdomain localhost
#127.0.1.1 mail.ltcom.it mail
192.168.0.151 mail.ltcom.it mail

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Many thanks !
