[Question] How to configure JMAP sorting to match IMAP (Roundcube) behavior for Inbox/Sent?

[bartfaizoli76]

Hi everyone,

I recently set up Stalwart Mail Server (v0.15.5) along with Bulwark Webmail (v1.4.12) using JMAP. I also have Roundcube set up via IMAP to the same Stalwart backend.

I've noticed a significant difference in how the Inbox and Sent folders are displayed between the two clients:

• Roundcube (IMAP): Displays all emails in the perfect chronological order (newest at the top).
• Bulwark (JMAP): Displays very old emails (from 2020, 2-4 years ago) at the top of these folders.

I checked the browser's network tab, and Bulwark is sending the following Email/query request, explicitly asking for descending order based on receivedAt:

"sort": [
  {
    "property": "receivedAt",
    "isAscending": false
  }
]

However, the server responds with a list of old email IDs first.

I have already tried checking "Disable Conversation Grouping" in Bulwark, but it didn't change the sorting for these specific, heavily populated folders.

Since IMAP works flawlessly with the exact same database, I assume my data is intact.

My question is:
Is there a specific configuration in config.toml (perhaps related to RocksDB, FTS, or JMAP indexing) that I need to tweak so JMAP respects the receivedAt sort order just like IMAP does? Or is there a way to force a reindex that specifically fixes JMAP sorting?

Thank you in advance for any guidance!
