in /etc/aliases:

devnull:  |/dev/null

and:

# ll /dev/null
crw-rw-rw-  1 root  wheel2,   2 Mar 19 11:13 /dev/null
but:

Mar 19 10:55:08 img10 postfix/local[41744]: 671235621: 
to=<[EMAIL PROTECTED]>, relay=local, delay=1, status=bounced (Command 
died with status 1: "/dev/null")

... is fixed with:

devnull:  |cat>/dev/null

 which gives:

Mar 19 11:13:51 img10 postfix/local[43231]: E5C4A5623: 
to=<[EMAIL PROTECTED]>, relay=local, delay=0, status=sent (delivered to 
command: cat)

Mar 19 11:13:51 img10 postfix/local[43231]: E5C4A5623: 
to=<[EMAIL PROTECTED]>, relay=local, delay=0, status=sent (delivered to 
file: /dev/null)

Piping into /dev/null has worked in the past, wondering why the cat command 
has become necessary?

Because /dev/null is not a program (it's a file), and cat is.  
You should only pipe to programs.

I think variant with cat is better, if you want without it
better will be
devnull: /dev/null
the latter works, thanks, Nik,

If you you have a minute, say why the cat step is better than just /dev/null

Maybe because is match piping to program not file?
