Hi to all,
Should I do a particular configuration with postfix and i need help.
I have a ldap server configured like this:

root Suffix dc=example,dc=com
  |
  | -----> Company1
dc=company1,dc=example,dc=com
  | | -----> domain1.1
 o=domain1.1,dc=company1,dc=example,dc=com
  | | -----> domain1.2
 o=domain1.2,dc=company1,dc=example,dc=com
  | | -----> domain1.3
 o=domain1.3,dc=company1,dc=example,dc=com
  | | -----> domain1.4
 o=domain1.4,dc=company1,dc=example,dc=com
  |
  | -----> Company2 dc=company2,dc=example,dc=com
  | | -----> domain2.1
 o=domain2.1,dc=company2,dc=example,dc=com
  | | -----> domain2.2
 o=domain2.2,dc=company2,dc=example,dc=com
  | | -----> domain2.3
 o=domain2.3,dc=company2,dc=example,dc=com
  | | -----> domain2.4
 o=domain2.4,dc=company2,dc=example,dc=com
  |
  | -----> Company3 dc=company3,dc=example,dc=com
  | | -----> domain3.1
 o=domain3.1,dc=company3,dc=example,dc=com
  | | -----> domain3.2
 o=domain3.2,dc=company3,dc=example,dc=com
  | | -----> domain3.3
 o=domain3.3,dc=company3,dc=example,dc=com
  | | -----> domain3.4
 o=domain3.4,dc=company3,dc=example,dc=com
  |
..................

For each company there can be N domain. And i have N company.
In my particular configuration i can that the domains that are in
Company1 can send email only to the domain that are in Company1. The
domains that are in company2 can send emails only the domains that are
in company2, and the domains that are in company3 can send emails only
the domains that are in company3.
The problem is that i don't know the company of the domain, but i can
know it only with a search ldap.
In this case i should make two search ldap.
First to get a base DN of the company. and second (binding on comany DN)
to get the domains of the company. Is correct??
I know that postfix is not able to make it. Is correct?
How can I fix? Any ideas?

Thanks
