Is it safe to remove hostname.mboxlist.date directories ?

Hi,

I have several old hostname.mboxlist.date directories besides one mboxlist directory in msg-store-base/data/store directory. Can anybuddy tell me is it safe to remove these old directories. Its my production server and I can't take any risk for user's db corruption.

Thanks in advance.
