Slightly off-topic question about handling unique identifiers

[harleay]

Hi,

Sorry if this goes a bit outside pure email topics, but the logic feels close to how identities are handled here.

I recently looked into how animal RFID microchips work, similar to what's explained when discussing microchipping your cat. The chip itself only stores a unique ID and all real information lives in an external database that gets queried when the chip is scanned. It reminded me of how Roundcube acts more like an interface while IMAP remains the actual data source.

I'm wondering if anyone ever used Roundcube as a lightweight interface to consult external identifiers stored somewhere else, not emails but things like inventory IDs or badge references tied to another system.

I'm not sure if this would make sense from a security or performance perspective, so I'm curious if any admins experimented with something similar or maybe rejected the idea for good reasons.

Thanks.
