> In relation to event notifications that include a mailbox uri (almost all of them), I have the following questions;

We didn't faced this issue because we aren't using Other and Shared
namespaces :(

Not sure that 'imap://' is right
because the format defined in the RFC 5092 - IMAP URL :

>             imap://<iserver>/<enc-mailbox>[<uidvalidity>]<iuid>[<isection>][<ipartial>][<iurlauth>]
>             The <iserver> component common to all types of absolute IMAP URLs has
>                             the following syntax expressed in ABNF [ABNF]: [iuserinfo "@"] host [ ":" port ]

If user john is doing something to a user jane mailbox, the
notification should contain the user john in the field "user" and the
URI imap:// in the fields "uri" and
"mailboxID". This is how I understand the RFC 5423.

I'm very glad that Event Notification feature is useful outside of our
