[Mimedefang] action_external_filter

Hi List,

There appears to be an issue with action_external_filter when there is
more than one attachment to an email.

The effect is that the body of the first attachment is replaced with
the last attachment processed.  I believe this is due to using
copy_or_link to copy the body to FILTERINPUT.  The first attachment
creates a hard link to FILTERINPUT, subsequent attachments do a copy
as the link exists.  The result being that when mimedefang finally
rebuilds the message the last FILTERINPUT content is used for the body
of the first attachment.

Best regards,
