Currently looking into the following questions:

- can I get the rfc 5423 type of event somehow (obviously I can set it on the event myself depending of the function called) event.name

...

- looking at the example code, it looks like it can be called for multiple messages, when does that happen (LMTP send more then one)

still no idea, maybe Ake? I noticed that some events have the same uid-validity, are the from a single transaction, eg. I delete my Trash?

Because these events also apply for more than just LMTP. You could be storing bunch of mails with IMAP APPEND.

...

- why is the mailbox status put into an other structure and send with a different notifiction

The LUA code very faitfully implements the C API for push notifications in Dovecot.

...

- does anyone have a code snippet to send a JSON encoded message (probably easy to figure out looking at Lua docu) these two I managed to solve im my current version of the script, which also support now all message event types:

<snip7>

This leads to a couple more questions ;) - is there a way (eg. return value) to stop event processing already in dovecot_lua_notify_begin_txn

There is no really good way to do this. You can error out in begin_txn, but that will emit error. The only doable way, right now, is to maybe add key {disabled=True} to your context, and then add if ctx.disabled: return elsewhere.

- sometimes multiple events are generated, eg. when I read an email: {"event":"FlagsClear","flags":[],"folder":"INBOX/eGroupWare/calconnect","imap-uid":2275,"imap-uidvalidity":1499767470,"keywords-old":[],"user":"user=5::42;***"} {"event":"FlagsSet","flags":["\\Seen"],"folder":"INBOX/eGroupWare/calconnect","imap-uid":2275,"imap-uidvalidity":1499767470,"user":"user=5::42;***"} {"event":"MessageRead","folder":"INBOX/eGroupWare/calconnect","imap-uid":2275,"imap-uidvalidity":1499767470,"unseen":0,"user":"user=5::42;***"}

This is what happens when you read unseen mail.
