[cobalt-users] Virtual Site: No Mail Delivery

["Tim Bolt" <timbolt@xxxxxxxxxxx>]

Hello List!

Again I find myself needing to turn to your collective wisdom and experience . . .

Situation:
All mail to a couple of my virual domains stopped being delivered and gets bouced with a message along the lines of:


   ----- The following addresses had transient non-fatal errors -----
<webmaster@xxxxxxxxxxxxx>

   ----- Transcript of session follows -----
451 <webmaster@xxxxxxxxxxxxx>... domainxyz.com: Name server timeout
451 <webmaster@xxxxxxxxxxxxx>... www.domainxyz.com: Name server
timeout
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old

etc, etc, etc...

Had a real play with re-doing the DNS parameters in the control panel for that site.  Also changed, dropped added the www.domainxyz.com & domainxyz.com to the "site settings" in the Cobalt domain management interface.
Basically had as much of a go as I could through the interface.

Also noticed that there is no:  "/etc/virtusertable" file.
Should this worry me?  Other emails are working apart from a couple of domains.


Many thanks for any advice!
Tim
