Rick,
Here's a possibility:
(consider the following as development hints--try it on a test box first)
--install the two rpms from here...
http://mirror.contribs.org/smeserver/contribs/hmuhammad/--put the pseudonyms in a tab-delimited file
(read the 'Configuration/Contacts' panel for details--but don't enable the service yet)
--delete line 35 of /etc/e-smith/events/actions/ldap-contacts-import
(so make sure there are no 'regular' email address for your domain in the tab-delimited file--pseudonyms and non-your-domain addresses are OK)
--enable the service via the panel
The following would apply when accessing the LDAP directory
--local (regular) accounts would be found using
dc=local,dc=yourdomain,dc=com
--global (pseudonyms & external) accounts would be found using
dc=global,dc=yourdomain,dc=com
--all accounts would be found using
dc=yourdomain,dc=com
Other relevant issues are discussed here...
