dovecot - Dec 2011 - Can I block dovecot from deleting read messages, after being fetched?

Hi all,
Is there an option to disable (server-side) the deletion of read mails
after fetching them via POP3, regardless of the MUA config?

Here are the issues I'm facing:

   - my boss wants to force everyone into a server-side "no delete
   message"-policy, for archiving, auditing and backup&recovery
purposes
   - the requisite here is pop3, so imap is out
   - the mailusers are virtual users (held in a mysql db)
   - don't have the budget to set up a separate mail-arvhing server
   - don't want to use shaggy ways (aka immutable flag, r/w permissions for
   Maildirs, etc)

dovecot --version
2.0.15

Help?
Thanks!

The policy apparently doesn't cover archiving outgoing email ?

Typically you set up your SMTP service to 'BCC' an archive mailbox to  
achieve a complete archive of both incoming and outgoing mail.

Global ACL for INBOX that gives owner a read-only access would do it.

Or maybe http://wiki2.dovecot.org/Plugins/Lazyexpunge? That would work better if
the POP3 client can't handle keeping mails on the server (but instead keeps
on redownloading them).
