Anyway it is better to make the "allow" ACIs, not "deny"
ACIs.

As for your problem, here is what the ACIs should look like (supposing
that your groups are cn=INTERNET,ou=Groups,dc=example,dc=com and
cn=EMAIL,ou=Groups,dc=example,dc=com, ip adresses of your squid server
are 192.168.0.66 and 172.16.191.66, adresses of your email servers
192.168.1.100 and 192.168.1.101)

Delete all the default ACIs (for anonymous/authentified users) and
choose the attributes that you want to expose (attr1,  attr2...)

For INTERNET group :
aci: (targetattr = "attr1 || attr2")(version 3.0; acl "Enable
attributes to read for a certain ip adresses and to authentified
users";allow (read,search,compare)(((ip="192.168.0.66") or
(ip="172.16.191.66")) and (groupdn
"ldap:///cn=INTERNET,ou=Groups,dc=example,dc=com"));)


For EMAIL group :
aci: (targetattr = "attr1 || attr2")(version 3.0; acl "Enable
attributes to read for a certain ip adresses and to authentified
users";allow (read,search,compare)(((ip="192.168.1.100") or
(ip="192.168.1.101")) and (groupdn
"ldap:///cn=EMAIL,ou=Groups,dc=example,dc=com"));)
