Hi Len,

I ran your suggested command:

> awk '/qmgr.*queue active/ { print $7 }' /var/log/maillog |\
>    cut -d "@" -f 2 | cut -d ">" -f 1 | sort -f | uniq -ic | sort -rfn \
>    | egrep -i " b\."

It found three results.  Two were spam and one was legit.  The legit sender 
was (believe it or not) "[EMAIL PROTECTED]".  I am not 
fluent in regexp.  (The man page made my eyes glaze over.)  Would your 
suggested filter have allowed or disallowed that particular address?
