Currently you can't use a map on some places in smtpd.conf. Therefor
you need sometimes hold the content in a list and a map. For example
you want some recipients handle by a different action then others:

table specialvirt { a@example.com=alice@example.com, b@example.com=bob@example.com }
table specialrcpt { a@example.com, b@example.com }

action specialaction forward-only virtual <specialvirt>
action default mbox virtual <virtual>

match for rcpt-to <specialrcpt> for domain "example.com" action specialaction
match for domain "example.com" action default

It would be simpler when you could use the specialvirt table also for
the rcpt-to rule. There are a few places where such double uses of
tables are not posible because the config parser restrict this:

* src and helo-src
* match auth and userbase or auth table
* match mail-from and virtual (you might want to reject local recipients)
* match rcpt-to and virtual

Following patch would fix this.
