It actually is working quite well now, if you've followed previous threads/bugs....
If you want it dead, first remove this line from exim.conf:
command = /usr/bin/spamassassin -w $sender_address
Lock exim.conf (chattr +i)
....................
Then..... remove the &.spamassassin& placeholder file in the root of every cpanel account that has activated it, just in case.
Finally, wax the Mail::SpamAssassin perl module
(from within your .cpan directory structure and perl 5.6.1 structure)... that's up to your server.
And lastly.... chmod 0000 /scripts/installspam
chattr +i /scripts/installspam
Restart exim and that's golden.
/etc/rc.d/init.d/exim restart
:p
