Hi,
I recently started receiving the following non-delivery report for emails replied to outside senders (for a specific scalix user):
----------------------------- ERROR REPORT -----------------------------
Message could not be delivered to the following recipient:
test / internet
DDT1=RFC-822; DDV1=test@example.com;
because: 'X.6.0 Other or undefined media error' [OM 8960]
------------------------------------------------------------------------
Any ideas?
