Okay, firstly I haven't had to do any of this before, but it might actually
be correct, and it should give you an idea of how to solve your problem :)

First of all, use in main.cf:
recipient_canonical_maps = pcre:/etc/postfix/recipient_map.pcre

# /etc/postfix/recipient_map.pcre
# Rewrite domain+user to user - I don't think the address is re-run
# through trivial-rewrite, so add the domain here.
/^mailaccount\+(.*)@/	${1}@server.localdomain

And here in main.cf:
sender_canonical_maps = pcre:/etc/postfix/sender_map.pcre

# /etc/postfix/sender_map.pcre
# Rewrite user@ to mailaccount+user at isp.net
/^(.*)@/	mailaccount+${1}@isp.net

I'm ignoring the domain name in the sender_map.pcre above so I think
this should just fall out.

According to local(8), it now supports Maildir for mail_spool_directory
when you specify the trailing slash (support was added in snapshot release
20010701).

Hope that helps :) Read up on canonical(5) in particular...
