ok.. after a bit of messing around.. and a nice link at: 
http://www.tldp.org/LDP/abs/html/textproc.html

and Scots grep idea..

have come up with (long winded and probably a roundabout way):

tail -f /var/log/maillog | grep -v imapd |grep -v connection |grep -v 
processing|  \
    cut -d" " -f0,3,6,7,8,9,10| grcat conf.craig

which outputs:

21:43:03 clean message (-4.9/5.0) for craig at 8010.co.uk:510
21:43:26 clean message (-4.9/5.0) for craig at 8010.co.uk:510
21:44:18 identified spam (6.1/5.0) for sales at 8010.co.uk:510

close enough for me :)

thanks guys!
