Manual  intervention?  Not  at  all.  You  schedule it; it pushes your
aliases into LDAP alongside the regular users, so that the whole valid
recipient list can be queried over LDAP.

I  will  add, per usual, that a well-configured LDAP server can handle
millions  of  recipient  lookups per hour, and the claims of "too much
overhead"  are  FUDdy.  A  directory  server  is  optimized for direct
queries,  not  for  text  file  exports,  and  with a proper directory
client,  its  performance  will outstrip any dumb text file traversal.

[This  and  previous  posts  on  the  subject  are irrespective of the
budgetary  or  functional merits of the anti-spam gateway in use; I am
simply speaking of the recipient validation process.]
