[exim] relay still open

Hi all

after adding the acl to close relaying , i am still flagged as an open
relay in ORBL:-

domainlist local_domains = wits.ac.za
domainlist relay_to_domains =
*.wits.ac.za:dragonzone.za.net:timetwist.za.net:mu
d.za.net:wicca.za.net:wax.za.net:pagan.za.net:icam.za.org:fotim.ac.za:drastico.z
a.net:witsie.icam.za.org:gothicparents.za.net:nixxie.za.net:sehnsucht.za.net:dek
an.co.za:iaphys.org:iaphys.com:cosalc.ac.za
hostlist relay_from_hosts = 127.0.0.1 : 146.141.0.0/16


acl_smtp_rcpt = acl_check_rcpt

begin acl

# This access control list is used for every RCPT command in an incoming
# SMTP message. The tests are run in order until the address is either
# accepted or denied.

#acl_check_rcpt:
acl_check_rcpt:
    accept domains = +local_domains : +relay_to_domains
    accept hosts   = +relay_from_hosts

I am running exim 4.24-1 on port 10000 and Interscan Trendmicro on port
25 (OS=solaris 5.9)

Anyone have any ideas?

Rgds,
Hement
