A low maintanence/med cost option is something like mimesweeper, which as I
understand it has LDAP intergration as does exchange 5.5

LDAP address lists
MAILsweeper for SMTP software can use address lists built from an LDAP
directory. This provides automatic access to user information stored and
managed in a central directory. LDAP address lists provide a simple
mechanism for specifying an organizational group.
To maximize efficiency, MAILsweeper builds a cache of the members of
the address list when the Security Service is started. The contents of this
cache are refreshed at specified intervals. This refresh period should
reflect
the frequency with which changes are made to the contents of the LDAP
directory.
{/quote from msw user guide}
never done it , just know it exists......
you could set up two distribution lists in exchange , one allowed to send
one not and set a rule(s) in mimesweeper accordingly
Also have a look at the thread [FW1] LDAP Integration on this mailing list
