OK back to my main question.

I have skimmed the spec through several times. Thanks for clearing things up
regarding macros.

OK. Makes sense now.

Actually it does, though my earlier snippet was quite incomplete. I have since
revised
both the snippet and the actual conf.

OK, thanks for your suggestions.
This implementation returns accept for defers and deny for "accepts". Yes,
it gets a little confusing.
skip_grey and partial_grey are domain-dependent localpartlists.
I have made a revised, simplified version based on your previous post.
My ACL now looks like this:
defer
warn set acl_m_PROTECTION = ${lookup mysql{SELECT protection FROM
domain_settings WHERE domain_
name='$domain'}}
!senders = : postmaster
#defer condition = {if eq{acl_m_PROTECTION}{2} }
# !local_parts = +skip_grey
# acl = greylist_acl
#{ !local_parts = +skip_grey}}
# acl = greylist_acl
# !local_parts =
# acl = greylist_acl
#defer condition = {if eq{acl_m_PROTECTION}{3}}{yes}{no}
# local_parts = +partial_grey
# acl = greylist_acl
#accept condition = {if eq{acl_m_PROTECTION}{2}}{yes}{no}
# !local_parts = +skip_grey
# acl = greylist_acl
#defer condition = {if eq{acl_m_PROTECTION}{1}}{yes}{no}
acl = greylist_acl
message = Greylisted
But this is not really going to work either. Essentially what I'm looking
for are if statements.
something like the meta code below:
if acl_m_PROTECTION == 2:
# do not protect these local parts
!local_parts = +skip_grey
acl = greylist_acl
elsif acl_m_PROTECTION == 3:
# protect only these local parts
local_parts = +partial_grey
acl = greylist_acl
Is something like this doable in ACLs?
