1) Please post your question in a new forum topic, do not hijack other's topic.
2) The latest RC release of Amavisd, 2.8.2-rc1, has a new LDAP attribute (amavisDisclaimerOptions) which is used to store per-user disclaimer options, you can try it on a testing machine.
As far as i know, Amavisd-new-2.8.0 supports this LDAP attribute, but the LDAP scheme file provided by Amavisd doesn't have this attribute, you can manually add this attribute and it should work as expected. Here's related discussion in Amavisd mailing list:
