Hi !

Here ar some questions from a newbie, could someone help me and/or has some
examples for me

1. is it possible to decide in a system filter whether an email has (,and
only has) an attachment or not ? how ?

2. how can i forward an email in a system filter without causing an infinite
loop (deliver ?)
    how do i prevent an infinite loop

3. which is the right way to forward emails for a group of users to one
email address: 
  aliassing or a system-wide .forward file  
   eg.
       a@??? ----->
       b@??? ----->
       .                    ----->          groupname_1@???
       .                    ----->
       h@??? ----->

       i@??? ----->
       j@??? ----->
       .                    ----->          groupname_2@???
       .                    ----->
