[cobalt-users] Host unknown error

["Justin Johnson" <justinj@xxxxxxxxxxxxx>]

 Has anyone seen this before?

 I have to raq's a raq3 with raq 4 OS and a raq4r with the 550 OS. Tey are
 connected with fixed IP's to my DSL connection and have them as NS1 and NS2
 name servers.

 Any domains I activate on the RaQ3 wok fine. With the RaQ4 all works fine
 apart from the email side. When I send mail to any addresses on this box,
 the mail is returned with the following error:

 ----- Transcript of session follows -----
 550 5.1.2 <sam@xxxxxxxxxx>... Host unknown (Name server: snjj.co.uk.: no
 data known)

 The most perplexing thing is, one domain I added worked fine. I did not
 (seem) to do anything any different and checked all the settings for this
 against the others but no joy.

Anyone have any ideas on this?

 Thanks in advance.
