I recently found a pretty good, albeit very dated book on Cyrus IMAP:

     "The Book of IMAP" by Peer Heinlein and Peer Hartleben

It also includes general chapters on the IMAP protocol (useful) and 
Courier IMAP (not so useful).

 From the description given in this book, it does appear that Cyrus 
notifyd has limited utility.  Some of the information appears to be out 
of date.

According to the book, if notifyd is running, the imapd.conf variables 
sievenotifier and mailnotifier determine whether (and what kind of) 
notifications you receive.

The imapd.conf man page for my version of Cyrus 2.4.17 does not include 
a description of mailnotifier, so presumably this option has been dropped?

As far as I can tell, through sieve you can be notified either via 
email, SMS or jabber/XMPP.  There is apparently no documentation for how 
to send SMS/XMPP messages.  Setting the sievenotifier option allows you 
to set a :method specification which overrides the default setting for 
sieve scripts.  They give this example:

     require "notify";
     if header :contains "from" "boss at example.com" {
         notify :method "mailto" :options ["paul at example.com"]
                :message "The boss has sent a new email";
     }


I hope I got that right.  The SMS/XMPP thing could be useful if it were 
documented.  I'm not sure I'm seeing the utility of the sievenotifier 
setting (send an email to let you know an email has been sent?).

I still have no idea how the Fastmail notifyd works or how this is 
integrated with calendar functionality.
