What I do is I implement a delivery lock in the database. I like to use
exim + mysql, but I think you can probably figure something out with
postfix + whatever, too.
In exim-ese:
mailbox_locked:
debug_print = "R: mailbox_locked for $local_part@$domain"
driver = redirect
allow_defer
verify = false
retry_use_local_part = true
domains = +virtual_domains
condition = ${lookup mysql{select locked from mailbox where
localpart='${quote_mysql:$local_part}' and
domain='${quote_mysql:$domain}' and locked=1 and active}}
data = :defer: Delivery deferred, mailbox is locked
