RBL whitelisting not working

I have the following problem, at rblwhitelist I put some CIDR ip ranges to whitelist.

One ip 201.254.74.128 is being blocked, but I have the CIDR range 201.254.0.0/16 whitelisted at rblwhitelist.

Why is being blocked?

Here is my config:

At the top of exim:

domainlist rbl_bypass = lsearch;/etc/rblbypass
hostlist rbl_whitelist = lsearch;/etc/relayhosts : net-iplsearch;/etc/rblwhitelist
addresslist whitelist_senders = wildlsearch;/etc/exim_whitelist_senders

At ACL section:

deny message = Message rejected - $sender_fullhost is in an RBL, see $dnslist_text
!hosts = +relay_hosts
!authenticated = *
!domains = +rbl_bypass
!hosts = +rbl_whitelist
!senders = +whitelist_senders
dnslists = sbl-xbl.spamhaus.org : bl.spamcop.net
