Lottery SPAM eml

Hi!

The attached text/plain lottery spam takes minutes to finish. An idle machine
takes about 1 minute, a busy MX takes up to 5 minutes to scan this mail. It
hangs somewhere in the compiled body rules part. Regardless if sa-compile was
used.

It hangs on several SA 3.3.1 installation I have on at least Fedora 12 and
CentOS 5.4. Both with stock rules and sa-update'd rules and without any local
rulesets.

Till yet I was not able to track down the rule which is causing this.

-D rules shows:
....
Jun 23 11:14:13.627 [32046] dbg: rules: run_generic_tests - compiling eval
code: body, priority 0
Jun 23 11:14:13.627 [32046] dbg: rules: compiled body tests
.....
Jun 23 11:14:13.683 [32046] dbg: rules: ran body rule __LOTSA_MONEY_02 ======>
got hit: "1, 068.00 Dollars"
Jun 23 11:15:54.052 [32046] dbg: rules: ran body rule __HAS_ANY_EMAIL ======>
got hit: "o@yahoo.co.j"
.....

and this was one of the "idle" machines;-) At least before and after running
SA;-)

Regards, Wolfgang
