hosts

Code:

127.0.0.1 localhost.localdomain localhost atlas.manaxa.com
10.0.0.33 atlas.manaxa.com atlas www.manaxa.com mail.manaxa.com manaxa.com www.stecher.org mail.stecher.org stecher.org

# 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

and resolv.conf

Code:

domain manaxa.com
nameserver 10.0.0.138
#nameserver 194.109.6.66
#nameserver 194.109.9.99

10.0.0.138 is my speedtouch router to the adsl connection.

I've found one odd thing: If I do a dig on my server (from that server), I get the external IP returned, instead of the internal one. I tell the machine to use the hosts-file first (in hosts.conf), but it just goes straight out, finds the external IP, and doesn't come back in again.
The same goes for nslookups, it returns the external IP, and says the nameserver used is 10.0.0.138. How can I make my server check its hostsfile first?

 

Also, what's in your /etc/host.conf?

 

Hi Till,
Yes, I did: it just goes straight out on the net... (compare hosts-file posted earlier)

Maybe Courier IMAP broke? I can send out mails now again, but incoming still goes nowhere. In my mail.log I get errors like 10.0.0.33 address not listed for hostname atlas.manaxa.com, but it still connects (from unknown 10.0.0.33, which is my server on its internal ip-address), and then it connects and sends out the mail.
Mail sent to external mail address:

First mail arrives, second doesn't...

 

I think the problem is that you listed atlas.manaxa.com for two IP addresses in /etc/hosts. Please remove atlas.manaxa.com from the 127.0.0.1 line.

 

Nope, doesn't change anything. It looks like there's a loop somewhere:
mail comes in, sender does dns-lookup and gets external IP, mail gets delivered here, my mailserver goes looking for correct domain and looks up its own ip-address through an external server, so mail gets held up and passed to secondary mailserver. That mailserver does a lookup, finds my external ip, delivers the mail, and the proces starts again...
how do I break the loop?

Falko, you're the man! I can't figure out for the life of me why I need this switch all of a sudden, but it works.
Thanks a million guys, for sticking with me and for making me an even stronger believer in Linux and ISPConfig (ok, so I'm just really, really glad).
