[SOLVED] Local delivery used Split DNS, localhost problems

[vargadanis]

Hi!

I have a fresh install on my computer. I used Split DNS and set up a nonexistent domain name. It works fine. I can connect to the server and so on. The only problem is that I get errors when trying to send emails to the local domain.
The error message is:

lost connection with 127.0.0.1 while recieving initial server greetings

What is this? I suppose it is a postfix error, right?
The unique about this install is that it is Ubuntu8.04 with a custom patched kernel (version 2.6.22-vs2.2.0.7). I patched it for use with Linux-Vserver. The vserver runs Hoary as well.

Thanx a lot in advance

The usual questions, what do the following commands show:

cat /etc/hosts
cat /etc/resolv.conf
host `hostname`  <-- type that command and use backticks not single quotes
dig yourdomain.com any
dig yourdomain.com mx

and post the output. How much RAM is on this Zimbra server?

Hi!

I didn't know it was important in this case, bere here you go:

root@dreamact:~# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.10 mail.dreamact.hu mail dreamact.hu

root@dreamact:~# cat /etc/resolv.conf
### BEGIN INFO

# Modified_by: NetworkManager
# Process: /usr/bin/NetworkManager

### END INFO

search dreamact.hu
#search mail.danis.myip.hu

nameserver 192.168.1.10
#nameserver 213.46.246.53
#nameserver 192.168.1.1

root@dreamact:~# host `hostname`
dreamact.hu has address 192.168.1.10
dreamact.hu mail is handled by 10 mail.dreamact.hu.

root@dreamact:~# dig dreamact.hu any

I hope these infos can help you

Apart from this line:

192.168.1.10 mail.dreamact.hu mail dreamact.hu

which should read this:

192.168.1.10 mail.dreamact.hu mail

the configuration seems OK.

How much RAM is on this server? Are there any other errors in the log files? Do you get this message all the time? It's only for sending local mail that you see this message, sending external mail works OK?

[edit]
Sorry, I forgot to ask if you could post the exact error message you're getting.

Hi!

The server has more than enough ram. I use only 50% of it as of now. 2GB..
I cannot send mails to outer domains as the domain I testing the install against is not registered. Yet local delivery should still work, shouldn't it?

That was an attempt to send mail:

[edit]
When I do telnet 127.0.0.1 25 I get response from the SMTP server...

This is likely to be the cause of your problem. I don't know much about Ubuntu but what's causing that error - firewall or SElinux?

[vargadanis]

I don't have either. I have no SELinux and no firewall...

[y@w]

Ubuntu 8.04 comes with apparmor out of the box. There's a good chance that's causing an issue. Try disabling that.

/etc/init.d/apparmor stop

[vargadanis]

Thanx for the tip but I don't have that installed either. I have a minimalistic ubuntu env. Zimbra in itself was bigger than the used env all together.

[Edit]

root@dreamact:/opt/zimbra/log# dpkg -l | grep appar
root@dreamact:/opt/zimbra/log#

[y@w]

Hmm ok. Anything in /var/log/messages?
