Weird Problem with MailScanner

[Damian Rivas]

Ok I finally understand what this
tutorial(http://elqui.dcsc.utfsm.cl/util/email/backscatter.html) means
in the parts I pasted before. According to that document you have to
specify the valid addresses one by one and the backscattering filter
just catch all the rest and throw them to trash.

######################
## Reject Backscatter....
# reject unknown recipients, because SPAMMERS use this to spam other
# domains through bounces messages (user unknown).
#
##############################################
# general rejection strings 
To:example.com error:5.1.1:"550 User unknown"
To:my.org error:5.1.1:"550 User unknown"
#
################################################
# Valid internal EMAIL addresses
#
To:john.doe at example.com RELAY
To:jane.joe at my.org RELAY
To:postmaster at example.com RELAY
etc...

The problem with this is that I have too many addresses and it would be
really tedious to write them all, aren't there a more human and nice
way?

Oh and by the way, thanks Kevin I've managed to configured filtering in
my MS Exchange server, thanks for the documentation!

My sendmail is 8.12.11, greet pause was released only for 8.13 versions
or are there some for the latest 8.12?
