Issue Description
I configured the following sieve script in my mail account:
if header :contains "List-Id" "rust-for-linux.vger.kernel.org" {
fileinto :create "R4L";
stop;
}
Expected Behavior
It should create a single R4L mailbox and direct all emails whose List-Id matches rust-for-linux.vger.kernel.org into that folder.
Actual Behavior
It created 3 R4L mailboxes:
R4L - 2 0
R4L - 1 1
R4L - 178 178
But in thunderbird, I could only see mails from the mailbox with 2 emails, other R4L mailboxes are inaccessible.
I think the number 3 here is not a coincidence. Perhaps each node in my cluster created one of them.
Reproduction Steps
- (Maybe) configure a 3 node stalwart cluster
- Configure a stalwart mail account to use the mentioned sieve script.
- Subscribe that account to Rust for Linux mailing list.
- Observe the number of mailboxes

I didn’t find too much information in the logs. Could you provide some information about what to grep?
