I would suggest you making exim (MTA) deliver "via" procmail script.
[ e.g. via making exim support ~/.procmailrc ]
In procmail script you can use external perl script to generate
"rotated" destination. You can use procmail locking or locks in perl to
avoid "race conditions".

The above simple solution is:
a) portable - it should work with almost all unix/linux MTAs
b) is appropriate unless you expect *HUGE* load
