domain (real + virtual) mapping question

From: Richard Foley (Richard.Foleyrfi.net)

I'm using postfix with 2 domains: a main "rfi.net" domain, and another virtual
domain.

The main domain is handled via /etc/postfix/aliases linked to /etc/aliases,
and has hard-wired "name"s on the left-hand side, with existing system user
accounts on the right-hand side, as the default setup, plus several entries
for explictly diverted majordomo aliases. And works fine, eg:

        hostmaster: root

# main.cf has:

        alias_maps = hash:/etc/postfix/aliases

The virtual domain is handled via /etc/postfix/virtual_alias_maps, and this
uses regexes to map particular name.patterns to various user accounts. And
works fine, eg:

        /name\.\w+virtual.net/ userhost.virtual.net

My problem is that I would like to have the 'main' domain also able to use a
regex to divert email to particular user accounts, which description in the
docs is eluding me. If I place the main domain in the virtual table, postfix
rightfully complains about not mixing incompatible configurations, but if I
put the main domain in the aliases table, I appear to lose the regex
facility... I hope this is clear? What I very simply want to do is this:

        /name\.\w+main.net/ userhost.main.net

I'm sure it's something obvious in the docs, but being a postfix newbie, I am
simply lost amongst all the virtual domains, virtual aliases, alias_maps,
aliases, transport_maps, etc. etc. If anyone has a simple hint which could
help clarify the situation, I'd greatly appreciate it.

TIA.
