Recipient Whitelist not working

Hello guys!

I did manage to get the sender part working:
To only send to the domain1 and domiain2

global_smtp_from_blacklist.map
/^.@.$/i

global_smtp_from_whitelist.map
/^.@domain1.com.br$/i
/^.@domain2.net.br$/i

However, I did the samething to the both global_rcpt_blacklist.map and global_rcpt_whitelist.map, but I keep receiving emails from all the domains.

I just need to send and recieve emails of both domains (domain1 and domain2).

Any help?
