Just block the subnet 116.203.180.0

route:          116.203.180.0/22
descr:          MTS-NEW-22-110
origin:         AS131222
mnt-by:         MAINT-MTS-INDIA-IN
changed:        dr.goyal at mtsindia.in 20110522
source:         APNIC

If spammy attempts also came from some 116.203.0.0
other than 116.203.180.0 then block the whole thing.

Makes life easier (I silently drop all SMTP connections
from *.cn on my server, after receiving gazillions of spam
emails without a single valid message, life's better now).

Note that with our current setup a single malicious account
can wreak havoc in /draft/
This is bound to happen.
