Hi there

And while you are at it:

smtpd_recipient_restrictions =
[...merge with current settings...]
reject_rbl_client sbl-xbl.spamhaus.org,

And to save some cycles, why not try:

iptables -A INPUT -j DROP -s 200.0.0.0/8
iptables -A INPUT -j DROP -s 210.0.0.0/8
iptables -A INPUT -j DROP -s 211.0.0.0/8
iptables -A INPUT -j DROP -s 218.0.0.0/8
iptables -A INPUT -j DROP -s 219.0.0.0/8
iptables -A INPUT -j DROP -s 220.0.0.0/8
iptables -A INPUT -j DROP -s 221.0.0.0/8
iptables -A INPUT -j DROP -s 222.0.0.0/8

(Nothing to do with blocking unqualified domains, but it blocks
billions of spam emails for me and that was the OP's problem... :)
