[cobalt-users] User Unknown - only happens sometimes..

["Cobalt - Rishi Gangoly" <cobalt@xxxxxxxxxxxxxxxxxxx>]

Hi

I have a Cobalt RaQ4 hosting about 15-20 domains...

I get an error message : User Unknown (See below)

However, if I send email to mayank@xxxxxxxxxxxxxxxxxxxxxxx it does not give
an error.

I'm not sure why this happened.

Has anyone had any similar experience?

Do I need to worry?

Regards

Rishi
