> h3. Why?
> This could be a usefull administrative feature, for instance offered by Dovecot:
> (credits chatgpt)
> {code:java}
> Dovecot: Provides robust administrative tools, including the doveadm who command, 
> which lists all currently connected users. This functionality is exposed via the Dovecot 
> Admin socket rather than an HTTP API.
> {code}
> Given JAMES-4090 we already track opened channels, exposing the users would thus be doable easily.
> Ref https://manpages.ubuntu.com/manpages/focal/man1/doveadm-who.1.html
> This is useful for diagnostic purposes.
> h2. API proposal
> {code:java}
> curl -XGET /servers/channels/[email protected]
> {code}
> Would return all channels belonging to `[email protected]`:
> {code:java}
> [
>    {
>        "protocol": "IMAP",
>         "endpoint": "imap-ssl",
>         "encrypted": true, // SSLHandler part of the pipeline
>         "connectionDate": "2024-11-20T16:00:00Z", // Tracked via an attribute to set upon connection
>         "remoteAddress": "12.23.45.43:4378",
>         "isActive": true,
>         "username": "[email protected]",
>         "protocolSpecificInformation": {
>              "compressed": "true", // CompressHandler part of the pipeline
>              "userAgent": "outlook", // Record then read this in the IMAPSession
>              "selectedMailbox": "INBOX", // Read the IMAPSession
>              "isIdling": "true",  // Inspect behavious in protocol overrides
>              "requestCount": "1234"  // channel attribute to be incremented on channelRead
>          }   
>    },
>    {
>        "protocol": "SMTP",
>         "endpoint": "smtp-server-global",
>         "encrypted": true, // SSLHandler part of the pipeline
>         "connectionDate": "2024-11-20T16:00:00Z", // Tracked via an attribute to set upon connection
