Hm.
I've just constructed such case:

    # head -1 /etc/aliases
    mobst: :include:/tmp/mobst

    # cat /tmp/mobst
    mobst       (it's a local user)
    heiko       (it's a local user)


    # exim4 -v -bv mobst
    [EMAIL PROTECTED]
        <-- [EMAIL PROTECTED]
      router = localuser, transport = local_delivery
    [EMAIL PROTECTED]
        <-- [EMAIL PROTECTED]
      router = localuser, transport = local_delivery


    # exim4 -bV

So - I can't see that duplicate delivery *would* happen. What does
'exim4 -v -bV' show on your system?
