See http://www.postfix.org/POSTSCREEN_README.html and
http://rob0.nodns4.us/postscreen.html
It's infortunate that smtpd(8) cannot be chrooted any longer, which
means that we have to un-chroot cleanup(8) as well. Indeed, currently
smtpd(8) uses $virtual_alias_maps for recipient validation; later
cleanup(8) uses it again for rewriting. So these processes need to be
both chrooted, or both not.

We can therefore spare some lookups on the MDA, and use static:all
instead.

Postfix interprets Error Code 32 (No Such Object) as lookup failures,
but that's ugly...
Also, make Postfix simple bind against
cn=postfix,ou=services,dc=fripost,dc=org.

So our suffix is now a mere 'dc=fripost,dc=org'. We're also using the
default '/var/lib/ldap' as olcDbDirectory (hence we don't clear it
before hand).

E.g., ldap.fripost.org, ntp.fripost.org, etc. (Ideally the DNS zone
would be provisioned by ansible, too.) It's a bit unclear how to index
the subdomains (mx{1,2,3}, etc), though.

Which might be caused by slow LDAP lookups in transport_maps. Instead,
we alias each addresses for which we want a custom transport to a
dedicated "dummy" domain, and use a static (CDB) transport_maps to map
said domains to their transport; the receiver can then use canonical(8)
to restore the original envelope recipient. Since the alias resolution
is performed by cleanup(8), which can run in parallel with other
instances, it should decongestion bottlenecks under heavy loads.
So far only the MX:es have been decongestioned. The list manager and
the MDA should be treated as well.

We introduce a limitation on the domain-aliases: they can't have
children (e.g., lists or users) any longer.
The whole alias resolution, including catch-alls and domain aliases, is
now done in 'virtual_alias_maps'. We stop the resolution by returning a
dummy alias A -> A for mailboxes, before trying the catch-all maps.
We're still using transport_maps for lists. If it turns out to be a
bottleneck due to the high-latency coming from LDAP maps, (and the fact
that there is a single qmgr(8) daemon), we could rewrite lists to a
dummy subdomain and use a static transport_maps instead:
virtual_alias_maps:
mylist@example.org -> mylist#example.org@mlmmj.localhost.localdomain
transport_maps:
mlmmj.localhost.localdomain mlmmj:
