[Exim] added IP to relayhosts file are deleted...

Hi!

I need to add an IP address to the relayhosts file, so that IP can send mails without SMTP athentication... (that´s right?)

I add it, restart the exim server and the added line (IP) is erased... any idea about this?


in other way, I have added the IP address to the
hostlist relay_hosts
line at exim.conf...

hostlist relay_hosts = lsearch;/etc/relayhosts : \
    localhost : THEIPADDRESS

?
TIA, and sorry for the bad english...
