[cobalt-users] RaQ3 Authentication Failures after Customer Installs Firewall

[David <david_dean@xxxxxxx>]

Scenario: Customer installs private network, complete with firewall and
masquerading. Immediately the customer can no longer connect to retrieve email
from their domain housed on our systems. Customer complains:

>Your mail server seems to require some kind of different 
>configuration than standard for e-mail clients,

Of course it must be "our" problem since they can no longer connect after
setting up a new network and firewall. <geezzz>

Any suggestions or input on how to resolve this issue? Are the authentication
failures resulting from sendmail (on the RaQ3) trying to perform reverse
lookups or is it rejecting the connection because they're masquerading their
network?

Thanks for any advice

David
