IPA-SERVER mail distribution list

I'm trying to configure the IPA-SERVER as mail distribution list.

From several email clients I'm able to pull email address from the IPA/LDAP server and use the autocomplete function. It is not clear to me how to configure groups distribution list into the IPA/SERVER and adopt the same mechanism to pull groups out from the IPA-SERVER from e-mail clients.

My base search for the ldap client is cn=accounts,dc=mydomain,dc=com I wonder If I need another search for cn=groups,cn=accounts,dc=mydomain,dc=com.

Should I define a special group within the IPA-SERVER with specific properties that allow the group to be searchable by e-mail clients?

Any help is greatly appreciate

Thank you
