How to enable multi accounts?

[cloudwishcom]

Hello

Is there any way to enable multi-account support so I will be able to connect multiple JMAP accounts or so?

Thank you.

Do you mean on JMAP Server (and Login) with multiple JMAP Account (in this session). Or multiple Logins (on the same Server or different)?

The first one is really nice stalwart support Group and Lists and this is listed in the same JMAP-Session as different accounts.
