Ah, I had never realized there is a debug option for the IMAP server. 
Thank you!

I modified my backends.local.php and the IMAP debug log output is below, 
beginning with a successful authentication: (FWIW, our 'advanced' IMAP 
server config from backends.local.php is at the end of this email.)

As you can see, the problems begin with the LIST command syntax.  But 
what really borks my mind is neither Cyrus nor Horde has been updated in 
the past few weeks, and this has been working fine until this past Saturday.
