Sorry, I made the conversion in my head when I wrote the E-mail. My 
whiteexp was and is 864, which equals 36 days (hence where the 36 came 
from).

-G 10:12:864
passtime = 10 minutes
greyexp = 12 hours
whiteexp = 864 hours (36 days)

I'll keep an eye on things and see if all is ok. I'm still concerned 
that there are too many legit senders not being whitelisted.

Also, after a change to the flags in rc.conf is 
/usr/local/etc/rc.d/obspamd restart sufficient for the changes to take 
effect or must I do a killall -HUP?


Thanks for your reply,
