We use Cyrus instead of a traditional mail store, and my colleague David
Carter extended it to reduce the damabed caused by careless users. Have a
look at the delayed expunge feature and the documentation for cyr_expunge
and unexpunge in Cyrus 2.3.1.
If you want to keep delivering into maildirs, I'd suggest patching Exim.
