By default, exim uses colon as its list separator.  So "::1" is "empty
item, :1", "0000:0000::1" is "0000, 0000, empty item, :1", and so on.

Are you configuring the interface list via debconf, or by directly
editing the configuration?  afaics the debconf setup intentionally
switches the list separator to be semi-colon in order to avoid such
issues.
