[cobalt-developers] Multiple Servers

[MistaAviB@xxxxxxx]

Hi. We currently host all our customers on a raq3. We just got a few more 
raq4i's.

We want ALL new customers to use and upload to the raq4 (call it serverb), 
BUT use  dns records on the raq3 (Servera). We have already setup serverb to 
use dns on servera.

Problem:
All web works fine and so does ftp, but when you try sending email to a 
domain on serverb, it bounces:

   ----- The following addresses had permanent fatal errors -----
<test@xxxxxxxxxx>
    (reason: system config error)

   ----- Transcript of session follows -----
553 5.3.5 domain.com. config error: mail loops back to me (MX problem?)
554 5.3.5 <test@xxxxxxxxxx>... Local configuration error

The strange thing is, the emails go thru on SOME domains but not others? I 
know its not a relay problem.

My DNS records are as follows:
on servera:
 domain.com   A record:   64.65.56.122    
 www.domain.com   A record:   64.65.56.122    
 domain.com   mail is sent to the High priority mail server   domain.com  

and on serverb: (I set it up just to be safe)
DNS Settings for lupasoccer.com 
 
Start of Authority (SOA) Configuration       
 lupasoccer.com   A record:   64.65.56.122    
 www.lupasoccer.com  A record:    64.65.56.122    
 64.65.56.122/24      www.lupasoccer.com  

I only set it up the way i did above, because the domains that can take the 
email are setup like that too?

Can anyone help me? Do i need a ptr record for servera?

Thanks :-)
