Steps to reproduce:

I am not sure how to trigger it.
I get system warnings about the disk being full and then I see a nstmp file using 1TB.
I deleted it, and hours later it happened again.
This have happened a few times for me in the past few weeks, but it seems to be happening more and more.

Additional context:
I am using imap. The entire mailbox on the server is 9.9GB.
