Dovecot.sieve folder appeared - Account keeps showing "loading messages"


A new folder appeared in my folder list, named dovecot.sieve. When I click this folder, it stays in the status “Loading Messages”. This folder is not present on the server-side.

To Reproduce…

Steps to reproduce the behavior:

  1. Open Mailspring
  2. Verify there is a folder called “dovecot.sieve”

Expected Behavior

This folder should not be present in the folder list.



  • OS and Version: Pop_!OS 20.10
  • Installation Method: Snap
  • Mailspring Version: 1.8.0

Do you see that folder in other email clients (eg. Thunderbird)?

Sieve scripts (server-side email filters) are stored in a.dovecot.sieve directory server-side if the server is using Dovecot + Pigeonhole, but it’s weird that it’s appearing as a folder in an email client!

Hi @Daniel ,
I have just installed Thunderbird to try this out; this folder is not shown there.

Same problem on a private mx server, this “dovecot/sieve” “folder” blocks the scanning messages step, which makes Java take more than 300% of my CPU all the time.

I’m on Ubuntu 20.04.
