📄 Description

Description

Based on a discussion from the Stalwart GitHub issue https://github.com/stalwartlabs/mail-server/discussions/477, it appears that Stalwart's IMAP server only indexes standard headers defined in RFCs and does not support searching custom headers (such as X-Auto-Bcc) by default. This design choice is intended to optimize server performance by maintaining a manageable index size, as most users typically search by common fields like recipients, subjects, or message contents.

Key Points

Custom Header Search Not Supported: Stalwart currently does not support searching for custom headers (e.g., X-Auto-Bcc) because these headers are not indexed.

A server_supports_custom_headers function is implemented to determine if the server supports searching custom headers. This function sends a test command to the server and inspects the response to check for support.
