Thanks! That's got me almost there. This works when I test with exim -be,
but in exim.conf, it fails with missing lookup type:

command = "/opt/lsoft/listserv/bin/lsv_amin /opt/lsoft/listserv/spool
${lookup ldap{ldap://
ldap.test.ualr.edu/ou=Lists,ou=Local,o=test.ualr.edu,dc=mail,dc=test,dc=ualr,dc=edu?cn?(mail=${quote_ldap:$local_part@$domain})}fail
}"
