Probably somewhat similar.

Umm. If it's allocating 500MB when deleting messages there's something
seriously wrong. I haven't heard this happening with any Dovecot version

With "deleting" do you mean marking messages as deleted, or the expunge
operation? With mbox or maildir? Does it matter how many messages you're
deleting? How large the mailbox itself is?
