[ILUG] blacklisting address

[Jason Corcoran]

Thanks,

I
Had implemented those ideas, the main problem seems to be some  
spanner(a) using a slight variation of 3 email addresses that were  
used sometime ago. I am the only user of this mail server so use a  
catch all address ( which causes it's own set of problems )

I think I need to tweak my header_checks file and test it using  
postmap -a

Thanks again,
Jason
