I'm still having issues with greylisting

First try:
Aug 31 11:27:59 hosting policyd: rcpt=122983, greylist=new, host=201.76.49.243 (hm1481-31.locaweb.com.br), from=xxxxx@ymidia.com.br, to=xxxx@prosoma.com.br, size=0
Aug 31 11:27:59 hosting postfix/smtpd[16781]: NOQUEUE: reject: RCPT from hm1481-31.locaweb.com.br[201.76.49.243]: 450 4.7.1 : Recipient address rejected: Policy Rejection- Please try later.; from= to= proto=ESMTP helo=

Second try:
Aug 31 11:33:12 hosting policyd: rcpt=123138, greylist=new, host=201.76.49.91 (hm1479-21.locaweb.com.br), from=xxxx@ymidia.com.br, to=xxxx@prosoma.com.br, size=0
Aug 31 11:33:18 hosting postfix/smtpd[28251]: NOQUEUE: reject: RCPT from hm1479-21.locaweb.com.br[201.76.49.91]: 450 4.7.1 : Recipient address rejected: Policy Rejection- Please try later.; from= to= proto=ESMTP helo=

Although the IP is different, I have policyd configured with

#
# greylist host address: default: off
#
# by default policyd will only use 3 octets when dealing
# with greylisting information. this allows policyd to
# work around roaming MTAs which are known to move mail
# between different queues after a 450/temp rejection.
#
# some dont want this functionality and wish to be more
# aggressive when receiving mail. example of the format
# of the ips stored:
#
# 1=192
# 2=192.168
# 3=192.168.0 <- default/recommended
# 4=192.168.0.1
#
GREYLIST_HOSTADDR=2

Any ideas on what else I could verify ?

Check section "Greylist Opt-in / Opt-out" in Policyd doc:

Not a good idea, spammers send out many SPAM with Gmail too.

Hello, I'm having some issues with the google and greylisting (may happen to other providers too)
In this case, @bravado.com.br is a google-hosted domain and @prosoma.com.br is an iRedMail domain
