I'm not an expert at Exim4 by any means... I'm guessing that there's some stanzas in a template somewhere that are missing that refer to this? Do they need to be added to the exim4.conf.template file? ... as I wrote this, I did one final Google search and located a forum thread from 2005 that says simply delete any IPv6 addresses from the "dc_local_interfaces" line... and discussed this whole not very obvious issue in detail.
