Scalix handles local domain as a case sensitive domain name

I just got a bounce for an email to our own domain, user@DOMAIN.com

----------------------------- ERROR REPORT -----------------------------
Message could not be delivered to the following recipient:

Administration / internet/CN=user
DDT1=RFC-822; DDV1=user@DOMAIN.com;

because: 'Recipient name not found at destination' [OM 9300]

Supplementary Information:

How do I add the capitalised version of our domain name to the Scalix server?

Domains must be handled case-insensitively by MTA's. It should not make a difference.

Thanks, the name of the group was not in fact the email address for the group as well.
