Re: [cobalt-users] Email Problem

[Edwin Groenescheij <edwin@xxxxxxxxxxxxxxxx>]

Hi,

Did you do a 'dig' or 'nslookup' for the MX record of the domains
at the DNS servers of the ISP's where things go wrong? I've had
it that the old ISP 'forgot' to remove the domain from it's DNS
and was still pointing at it's own mailservers. 

Cheers,
Edwin
