No. You need some external tool for making this. You can use 
"proxyservers" option for proxy account.

May be, you can use
ipurge -d 3 -i -s mailboxpattern
but, it can be dangerously.

Also, see:

And try to ask in cyrus-devel at lists.andrew.cmu.edu list for enabling 
this functionality in next releases.

WBR.
