I hadn't heard about that patch. But even without the patch,
you can do basically the same things. I have this in my
sendmail.mc:
define(`confBAD_RCPT_THROTTLE',`5')dnl
[...]
LOCAL_RULESETS
Scheck_data
# Reject if lots of bad addresses:
R $* $: $&{nbadrcpts}
R $+ $: $(arith l $@ $1 $@ 8 $)
R FALSE $# error $@ 5.1.2 $: "553 Too many bad recipients"
I guess this is getting a bit off-topic, though.
