[Dovecot] notification plugin

[Wolfgang Rosenauer]

Hi,

I'm pretty new to dovecot's codebase and trying to write a plugin
which performs certain plugins if new mail arrives in a user's mailbox.

I saw the mail-log plugin and was playing around with it but it seems
to not create events if new mails arrive but only if mail are copied
or saved from an IMAP connection.
Are there any hooks I can base my plugin on to get events in the
above case?
Any pointers?

Thanks,
 Wolfgang
