[exim] ACL and extract option

Hi

At the start of my exim config i have that list:

ACL_CONF=h172.16.1.14=smtp h172.16.1.13=smtp h77.252.144.151=smtp \
h172.16.1.2=fake h77.259.44.22=fake \
h77.259.44.23=mx h172.16.1.4=mx \
h77.259.44.24=mx h172.16.1.3=mx \
h=mx

After that:

acl_smtp_rcpt = acl_check_rcpt${extract {h$interface_address}{ACL_CONF}
{_$value} {} }
acl_smtp_mime = acl_check_mime${extract {h$interface_address}{ACL_CONF}
{_$value} {} }
acl_smtp_data = acl_check_data${extract {h$interface_address}{ACL_CONF}
{_$value} {} }
acl_smtp_predata = acl_check_predata${extract
{h$interface_address}{ACL_CONF} {_$value} {} }
acl_smtp_mail = acl_check_mail${extract {h$interface_address}{ACL_CONF}
{_$value} {} }
acl_smtp_helo = acl_check_helo${extract {h$interface_address}{ACL_CONF}
{_$value} {} }
acl_smtp_connect = acl_check_connect${extract
{h$interface_address}{ACL_CONF} {_$value} {} }
acl_smtp_quit = acl_check_quit${extract {h$interface_address}{ACL_CONF}
{_$value} {} }

After that acl rules:

begin acl

acl_check_connect_smtp:
........

acl_check_helo_smtp:
..........

This means that suffix 'smtp' with rule for example 'acl_check_helo'
relays with hosts from my first listing:

'h172.16.1.14=smtp h172.16.1.13=smtp h77.252.144.151=smtp'

and is not connected with:

h172.16.1.2=fake h77.259.44.22=fake \
h77.259.44.23=mx h172.16.1.4=mx \
h77.259.44.24=mx h172.16.1.3=mx \
h=mx

?

I tried to use `exim -be` but I'am a little bit confused how to check
this variables.

Regards!
