Could help a lot... The problem is to retreive the mail which has already 
been delivered to the "old" mailboxes.

I don't know of any good way to do that for a large number of POP accounts 
and heterogenous mail storage systems.

If you have a complete list of login / passwords you can use fetchmail to 
get the mail from the old accounts and send it to the new ones.

If you don't have such a list some tcpflow on port 110 with some filtering 
could give you most of the accounts (hopefully not too many people are on 
vacations and don't check their mails).

Good luck
